Cesar Cuenca (Ohio State):
The Symplectic Schur Process
Abstract: We introduce a new symmetric function that plays the role of skew Schur function for symplectic groups. Many combinatorial identities for this function are developed and employed to construct the Symplectic Schur Process. This new probability ensemble shares many desirable properties with the classical Schur process of OkounkovReshetikhin and we will explain some of them in this talk, including the property of being a determinantal point process, the connection to the Berele insertion algorithm and, finally, we discuss some applications. This talk is based on joint work with Matteo Mucciconi.

Jiaming Xu (University of Wisconsin):
Edge universality of Betaadditions through Dunkl operators
Abstract: It is well known that the edge limit of Gaussian/Laguerre Beta ensembles is given by Airy(\beta) point process. We prove an universality result that this also holds for a general class of additions of Gaussian and Laguerre ensembles. In order to make sense of Betaaddition, we introduce type A Bessel function as the characteristic function of our matrix ensemble, then extract its moment information through the action of Dunkl operators, a class of differential operators originated from special function theory. Joint work in preparation with David Keating.
 THURSDAY, February 29. 3:00pm in 2132
Yuhan Jiang (Harvard):
The doubly asymmetric simple exclusion process
Abstract: The multispecies ASEP (mASEP) is a Markov chain in which particles of different species hop on a onedimensional lattice. The doubly ASEP (DASEP) is like the mASEP, but it additionally allows spontaneous change of species. We will introduce two new Markov chains that the DASEP lumps to, which give relations between sums of steady state probabilities. We also give explicit formulas for the stationary distribution of a particular infinite family.
 THURSDAY, February 15. 3:00pm in 2132
Vidya Venkateswaran:
Quasipolynomial generalizations of Macdonald polynomials
Abstract: In joint work with Siddhartha Sahi and Jasper Stokman, we constructed (quasi)polynomial generalizations of nonsymmetric Macdonald polynomials for arbitrary reduced root systems. We will introduce these objects and discuss how they arise from a family of cyclic $Y$parabolically induced DAHA modules where the $T_i$ operators act via ``truncated'' divided difference operators. We will also connect a limiting case of these polynomials to metaplectic Whittaker functions, and discuss recent duality results between (anti)symmetric quasipolynomials and partially (anti)symmetric polynomials.
Talks in Fall 2023 (most recent at the top):
 THURSDAY, November 30. 3:00pm in 2132
Jimmy He (MIT): Random growth models with half space geometry
Abstract: Random growth models in 1+1 dimension capture the behavior of interfaces evolving in the presence of noise. These models are expected to exhibit universal behavior, but we are still far from proving such results even in relatively simple models. A key development which has led to recent progress is the discovery of exact formulas for certain models with a rich algebraic structure, leading to asymptotic results. I will survey some of these results, with a focus on models where a single boundary wall is present, as well as applications to rates of convergence for a Markov chain.
 THURSDAY, November 16. 3:00pm in 2132
Sveta Gavrilova (MIT): Grothendieck measures on partitions
Abstract: We study probability measures on partitions based on symmetric Grothendieck polynomials, which are certain deformations of Schur polynomials. Despite the similarity of determinantal formulas for the probability weights of Schur and Grothendieck measures, we demonstrate that Grothendieck measures are not determinantal point processes. This question is related to the principal minor assignment problem in algebraic geometry. We identify Grothendieck random partitions with a crosssection of a Schur process, which allows us to derive limit shape result. The limit shape curve is not particularly explicit as it arises as a crosssection of the limit shape surface for the Schur process. Also, by extending our approach, we introduce a new framework of tilted biorthogonal ensembles.
 THURSDAY, October 26. 3:00pm in 2132
David Keating (University of Wisconsin): Coupled tilings, double dimers, and LLT polynomials
Abstract: In this talk will begin by constructing coupled tilings of the Aztec diamond. These can be viewed as a pair of a tilings, superimposed one on top of the other, with a certain local interaction between the tilings. We will show how to use the underlying integrable structure to compute the generating function of these tilings. Then we will discuss some ways to combinatorially understand the multicolored nature of the model. We will then introduce the closely related LLT symmetric polynomials, defining them as colored, interacting copies of a five vertex model. Again, our goal will be to give some combinatorial understanding of interplay between the colors.
 THURSDAY, October 19. 2:30pm in 2132
Leonid Petrov (University of Virginia): Stationarity for Colored Interacting Particle Systems on the Ring
Abstract: Recently, there has been much progress in understanding stationary measures for colored (also called multispecies or multitype) interacting particle systems motivated by asymptotic phenomena and rich underlying algebraic and combinatorial structures (such as nonsymmetric Macdonald polynomials). I will describe a unified approach to constructing stationary measures for colored ASEP, qBoson, and qPushTASEP systems based on integrable stochastic vertex models and the YangBaxter equation. Stationary measures become partition functions of new "queue vertex models" on the cylinder, and stationarity is a direct consequence of the YangBaxter equation. Our construction recovers and generalizes known stationary measures constructed using multiline queues and the Matrix Product Ansatz. In the quadrant, YangBaxter implies a colored version of Burke's theorem, which produces stationary measures for particle systems on the line. We also compute the colored particle currents in stationarity. Joint work with Amol Aggarwal and Matthew Nicoletti.
 THURSDAY, September 28. 1:00pm in 2429
Patrik Ferrari (Bonn): TASEP with a moving wall
Abstract: We study TASEP on Z with the step initial condition, under the additional restriction that the first particle cannot cross a deterministically moving wall. We prove that such a wall may induce asymptotic fluctuation distributions of particle positions equal to the probability that the Airy2 process is below a barrier function g. This is the same class of distributions that arises as onepoint asymptotic fluctuations of TASEPs with arbitrary initial conditions.

Catherine Wolfram (MIT):
Large deviations for the 3D dimer model
Abstract: In 2000, Cohn, Kenyon, and Propp showed that 2D dimer tilings satisfy a large deviations principle. In joint work with Nishant Chandgotia and Scott Sheffield, we prove an analogous large deviations principle for dimers in 3D. A lot of the results for dimers in two dimensions use tools and exact formulas (e.g. the height function representation of a tiling or the Kasteleyn determinant formula) that are specific to dimension 2. I will explain how to formulate the large deviations principle in 3D, show simulations, try to give some intuition for why three dimensions is different from two, and explain some of the ways that we use a smaller set of tools (e.g. Hall’s matching theorem or a double dimer swapping operation) in our arguments.
 THURSDAY, September 14. 3:00pm in 2132
Lingfu Zhang (UC Berkeley): Random Lozenge Tiling at Cusps and the Pearcey Process
Abstract: It has been known since CohnKenyonPropp (2000) that uniformly random
tiling by lozenges exhibits frozen and disordered regions, which are
separated by the 'arctic curve'. For a generic simply connected
polygonal domain, the microscopic statistics are widely predicted to be
universal, being one of (1) discrete sine process inside the disordered
region (2) Airy line ensemble around a smooth point of the curve (3)
Pearcey process around a cusp of the curve (4) GUE corner process around
a tangent point of the curve. These statistics were proved years ago for
special domains, using exact formulas; as for universality, much
progress was made more recently. In this talk, I will present proof of
the universality of (3), the remaining open case. Our approach is via a
refined comparison between tiling and nonintersecting random walks, for
which a new universality result of the Pearcey process is also proved.
This is joint work with Jiaoyang Huang and Fan Yang.
Talks in Spring 2023:
 THURSDAY, March 16. 2:30pm in 2147
Jimmy He (MIT): Boundary current fluctuations in the half space ASEP
Abstract: The half space asymmetric simple exclusion process (ASEP) is an interacting particle system on the half line, with particles allowed to enter/exit at the boundary. I will discuss recent work on understanding fluctuations for the number of particles in the half space ASEP started with no particles, which exhibits the BaikRains phase transition between GSE, GOE, and Gaussian fluctuations as the boundary rates vary. As part of the proof, we find new distributional identities relating this system to two other models, the half space HallLittlewood process, and the free boundary Schur process, which allows exact formulas to be computed.
 THURSDAY, April 20. 2:30pm in 2147
Matthew LernerBrecher (MIT): Edge Limits of the Laguerre Corners Process at Zero Temperature
Abstract: In this talk, we will discuss the hard edge limit of a multilevel extension of the Laguerre $\beta$ensemble at $\beta=\infty$. In particular, we will see that this limit can be captured by a discrete time Gaussian process defineable in two different ways: (1) in terms of its covariance function and (2) in terms of the partition functions of certain additive polymers arising from Bessel functions. Our work here builds off GorinKleptsyn (2020), which studied the soft edge limit of the corresponding Gaussian case, and we will spend some time expounding on interesting connections that arose between our results and theirs.
 THURSDAY, April 27. 2:30pm in 2147
Ron Nissim (MIT): Asymptotics of the Onepoint Distribution for the KPZ Fixed Point Conditioned on a Large Height at an Earlier Point
Abstract: After a review of the KPZ universality class and the KPZ fixed point, we will discuss formulas for the multitime distribution of the KPZ fixed point with step and flat initial conditions obtained by Zhipeng Liu (2022). Via these formulas, I will address the asymptotics for one point conditioned on a large height at an earlier point. This is based on joint work with Ruixuan Zhang. Lastly, we will compare this to another asymptotic regime studied by Zhipeng Liu and Yizao Wang (2022).
 THURSDAY, May 4. 2:30pm in 2147
Matthew Nicoletti (MIT): Six vertex model and random matrices
Abstract: In this expository talk, we will introduce the six vertex model, a well studied quantum integrable lattice model of statistical mechanics, and on the other hand we will also introduce several universal distributions originating from the study of eigenvalues of various random matrix ensembles. In one special case, via the IzerginKorepin determinant formula, we provide a self contained proof of the appearance of one such universal eigenvalue distribution in a random six vertex configuration in the scaling limit.
 THURSDAY, May 11. 2:30pm in 2147
Gopal Goel (MIT): A QUANTIZED ANALOGUE OF THE MARKOVKREIN CORRESPONDENCE
Abstract: We study a family of measures originating from the signatures of the irreducible components of representations of the unitary group, as the size of the group goes to infinity. Given a random signature $\lambda$ of length $N$ with counting measure $\mathbf{m}$, we obtain a random signature $\mu$ of length $N1$ through projection onto a unitary group of lower dimension. The signature $\mu$ interlaces with the signature $\lambda$, and we record the data of $\mu,\lambda$ in a random rectangular Young diagram $w$. We show that under a certain set of conditions on $\lambda$, both $\mathbf{m}$ and $w$ converge as $N\to\infty$. We provide an explicit moment generating function relationship between the limiting objects. We further show that the moment generating function relationship induces a bijection between bounded measures and certain continual Young diagrams, which can be viewed as a quantized analogue of the MarkovKrein correspondence.
Talks in Fall 2022:
 THURSDAY, September 15. 3:00pm in 4153 (note: not building 2!)
Guilherme Silva (ICMCUSP): Differential equations for KPZ fixed points.
Abstract: We discuss how multipoint distributions of the KPZ fixed point with narrow wedge initial condition relate to matrix versions of NLS and mKdV systems, and also with matrix KP equation and KP hierarchy. Our approach is via integrable operators, and covers multipoint distributions for the KPZ fixed point, its periodic counterpart, and unravels common features of both of them in an unified way. As we will discuss, our results also contain previously found connections by Tracy and Widom, Adler and van Moerbeke, and others, in the context of the Airy2 process.
 THURSDAY, September 22. 3:00pm in 4153 (note: not building 2!)
Matteo Mucciconi (Warwick): A bijective approach to solvable KPZ models.
I will provide a detailed proof of the bijection at the core of our new approach to study KPZ models. A fundamental ingredient here is the notion of Kashiwara's crystals and their relation to the RSK correspondence, but also to discrete integrable systems such as the boxball system.
 THURSDAY, September 29. 3:00pm in 4153
Cesar Cuenca (Harvard): Random matrices and random partitions at varying temperatures
Abstract: We discuss the globalscale behavior of random matrix eigenvalues and random partitions which depend on the "inverse temperature" parameter beta. The goal is to convince the audience of the effectiveness of the moment method via Fourierlike transforms in characterizing the Law of Large Numbers and Central Limit Theorems. We focus on the regimes of high and low temperatures, i.e., when the parameter beta converges to zero and to infinity, respectively. This talk is based on joint works with Florent BenaychGeorges  Vadim Gorin, and Maciej Dolega  Alex Moll.
 THURSDAY, October 20. 3:00pm in 4153
Misha Goltsblat (Yale): Variations of Schur functions and classical group characters
In the 1992 paper “Schur functions: theme and variations” Macdonald listed nine variations of Schur functions. The 6th variation is the factorial Schur functions. The 9th variation unifies variations 4–8. Recently Foley and King defined factorial versions of the irreducible characters of the symplectic and orthogonal groups. They proved combinatorial formulas and certain flagged versions of the Jacobi–Trudi identity for their factorial characters. We will discuss how to prove the unflagged Jacobi–Trudi identities. This allows us to define symplectic and orthogonal versions of Macdonald’s 9th variation. Along the proof we will introduce another generalization of the symplectic and orthogonal characters, which provides the most general framework for the symplectic and orthogonal versions of the Cauchy identity to hold. We will also carry over this discussion to the case of nonpolynomial representations of GL(n).
 THURSDAY, October 27. 3:00pm in 4153
Patrick Lopatto (Brown): The Mobility Edge of Lévy Matrices
Abstract: Lévy matrices are symmetric random matrices whose entry distributions lie in the domain of attraction of an alphastable law; such distributions have infinite variance when alpha is less than 2. Due to the ubiquity of heavytailed randomness, these models have been broadly applied in physics, finance, and statistics. When the entries have infinite mean, Lévy matrices are predicted to exhibit a phase transition separating a region of delocalized eigenvectors from one with localized eigenvectors. We will discuss the physical context for this conjecture, and describe a result establishing it for values of alpha close to one. This is joint work with Amol Aggarwal and Charles Bordenave.
 THURSDAY, November 3. 3:00pm in 4153
Ryan Mickler (Singulariti): New results on the structure of Jack LittlewoodRichardson coefficients.
Abstract: In 2013, NazarovSkylanin introduced a quantization of the Lax operator $L$ of the BenjaminOno integrable hierarchy on the torus, a 1+1 dimensional classical integrable system of nonlinear dispersive waves. They showed that a particular matrix element of the powers of $L$ provide an infinite family of commuting quantum Hamiltonians which are diagonalised on Jack symmetric functions. We prove a spectral theorem for $L$, showing that its eigenvectors are polynomials which refine Jack symmetric functions. As a consequence, the products of these eigenfunctions refine the algebra of Jack functions. We study these refined products through the introduction of several of tracelike functionals, which reveal a surprising simplicity to the structure of the algebra. Using this technique, we find explicit closedform relations between Jack LittlewoodRichardson coefficients and prove several new cases of a conjecture of Stanley on the structure of these coefficients. [ In part joint work with Alexander Moll and Per Alexandersson (papers to appear in October) ]
 THURSDAY, November 17. 3:00pm in 4153
Zhengye Zhou (Texas A&M): Orthogonal polynomial dualities of multispecies ASEP and related processes via the $^*$bialgebra structure of quantum groups
Abstract: In this talk, I present a general method to produce orthogonal polynomial dualities from the $^*$bialgebra structure of DrinfeldJimbo quantum groups. In the case of the quantum group $\mathcal{U}_q(\mathfrak{gl}_{n+1})$, the result is a nested multivariate $q$Krawtchouk duality for the $n$species ASEP$(q,\boldsymbol{\theta})$. The method also applies to other quantized simple Lie algebras and to stochastic vertex models. As a probabilistic application of the duality relation found, we provide an explicit contour integral formula of the $q$shifted factorial moments for the twospecies $q$TAZRP.
 THURSDAY, December 1. 3:00pm in 4153
Roger Van Peski (MIT): Random groups, random matrices, and universality
Abstract: In this talk I will discuss some recent joint work (https://arxiv.org/abs/2209.14957v1) with Hoi Nguyen, which concerns a universal distribution on sequences of abelian pgroups arising from products of random integer matrices. I will explain the context for the result from number theory, random graphs, and complex random matrix products, and also give a general introduction to the ideas behind the `moment method for random groups' used to prove this and many similar results in the literature.
 THURSDAY, December 8. 3:00pm in 4153 (last talk of the semester)
Mackenzie Simper (Broad Institute): Double coset Markov chains
Abstract: Let G be a finite group. Any two subgroups H, K define equivalence classes of G called the `double cosets'. The sizes of double cosets can vary greatly (unlike single cosets), and the set of double cosets can be in bijection with interesting combinatorial objects. A Markov chain on the group induces a random process on the double coset space — I will present a sufficient condition for the induced random process to also be a Markov chain, and then discuss several examples. In particular, if G is the group of invertible matrices over a finite field, and H = K the subgroup of uppertriangular matrices, then the double cosets are indexed by permutations. The uniform distribution on G induces the Mallows measure on permutations, and multiplication by random transvections defines an interesting Markov chain on permutations which can be described using the Hecke algebra of double cosets. Based on joint work with Persi Diaconis and Arun Ram.

 THURSDAY, Feb 24. 4:00pm in 4261 (note: not building 2!)
Tomas Berggren (MIT): Domino tilings of the Aztec diamond with doubly periodic weightings
Abstract: In this talk we will discuss random domino tilings of the Aztec diamond with doubly periodic weights. More precisely, asymptotic results of the $ 2 \times k $periodic Aztec diamond will be discussed, both in the macroscopic and microscopic scale. The starting point of the asymptotic analysis is a double integral formula for the associated correlation kernel, which is expressed in terms of a matrix WienerHopf factorization. We will also see a close connection to an associated Riemann surface, with which we will describe the global picture.

 THURSDAY, March 10. 4:00pm in 4261
Sergei Korotkikh (MIT): Spin qWhittaker functions and vertex models
Abstract: I will tell about a new family of symmetric functions I've been working on, called inhomogeneous spin qWhittaker functions. They originate from a certain vertex model equivalent to qHahn TASEP and they generalize qWhittaker symmetric functions (t=0 degeneration of Macdonald functions). I will describe how these functions originated from integrable probability and will explain connections to some other families of symmetric functions, namely, spin HallLittlewood functions and interpolation symmetric functions. Time permitting, I will also cover the connection of the model with the representation theory of quantum affine sl_2.
 THURSDAY, March 17. 4:00pm in 4261
Mustafa Alper Gunes (Oxford): Moments of Characteristic Polynomials of Random Matrices, Painleve Equations and Lfunctions
Abstract: In this talk, we will consider various different types of joint moments of characteristic polynomials of random matrices that are sampled according to the Haar measure on classical compact groups. In each case, we will see how one can obtain the asymptotics of these quantities as the matrix size tends to infinity, and see the implications that these asymptotics have regarding moments of Lfunctions. Finally, we will see that these asymptotics have representations in terms of solutions of certain Painleve equations, giving us conjectures relating Lfunctions and solutions of these Painleve systems. Based on a joint work with Assiotis, Bedert and Soor, and some original results obtained as a part of my undergraduate thesis.
 THURSDAY, March 31. 4:00pm in 4261
Promit Ghosal (MIT): Universality of multiplicative statistics of Hermitian random matrix ensembles
Abstract: Multiplicative statistics of random matrix ensembles and their scaling limits are important ingredients for many findings throughout the last few decades. In this talk, we focus on large matrix limit of multiplicative statistics of eigenvalues of unitarily invariant Hermitian random matrices. We show that for onecut regular potential and a large class of multiplicative functional, the associated statistics converge to an universal limit which is described in terms of integrodifferential Painleve II equation. This talk will be based on a joint work with Guilherme Silva.
 THURSDAY, April 7. 3:00pm in 4261 (NOTE UNUSUAL TIME)
Guillaume Barraquand (ENS): Positive random walks in random environment
Abstract: We will consider random walks in random environment and discuss how their asymptotic behavior differs from that of simple random walks. I will first survey what is known about an exactly solvable model on Z, the Beta RWRE. Then I will show that there exists a variant of the model, where the walks are restricted to positive integers, which remains exactly solvable. The large scale behavior of this model present some similarities with the model on Z, but also some differences due to the presence of a boundary. This is a joint work with Mark Rychnovsky.
 THURSDAY, April 14. 4:00pm in 4261
Jimmy He (MIT): Shift invariance of some half space integrable models
Abstract: I'll discuss work in progress on shift invariance in a half
space setting. The starting point is the colored stochastic six vertex
model in a half space, from which we obtain results on the asymmetric
simple exclusion process, as well as for the beta polymer through a
fusion procedure. An application to the asymptotics of a type B analogue
of the oriented swap process is also given.
 THURSDAY, April 21. 4:00pm in 4261
Marianna Russkikh (MIT): Everything you always wanted to know about tembeddings*
*but were afraid to ask
Abstract: We introduce a concept of ‘tembeddings’ of weighted bipartite planar graphs. We believe that these tembeddings always exist and that they are good candidates to recover the complex structure of big bipartite planar graphs carrying a dimer model. We also develop a relevant theory of discrete holomorphic functions on tembeddings; this theory unifies Kenyon’s holomorphic functions on Tgraphs and sholomorphic functions coming from the Ising model.
 THURSDAY, April 28. 4:00pm in 4261
Terrence George (University of Michigan): Shufflings in the dimer model
Abstract: Dominoshuffling is a technique introduced by Elkies, Kuperberg, Larsen and Propp to enumerate and generate domino tilings of the Aztec diamond graph, and was used to give the first proof of the arctic circle theorem. Domino tilings are dual to the dimer model on the square lattice. There are generalizations of dominoshuffling for any biperiodic dimer model, and they form a group called the cluster modular group. This group was studied by Fock and Marshakov, who gave an explicit conjecture for its isomorphism type. We will discuss these generalized shufflings and describe the cluster modular group for any biperiodic dimer model. (joint work with Giovanni Inchiostro).
 THURSDAY, May 5. 4:00pm in 4261
Alexander Moll (UMass Boston): Exact Results for the Quantum BenjaminOno Equation on the Torus
Abstract: In this talk, we use a fractional Gaussian field on the 1dimensional real torus to quantize BenjaminOno waves and give a dynamical interpretation of a result of Stanley (1989). Precisely, the classical BenjaminOno equation on the torus is a nonlinear and nonlocal model of dispersive waves. Starting from the standard Gaussian in the symplectic space of this equation, we construct the quantum BenjaminOno equation on the torus without any path integrals. Remarkably, a result of Stanley (1989) for Jack polynomials implies an exact description of the spectrum of the quantum Hamiltonian in this model. We prove that if one considers BohrSommerfeld quantization of the classical BenjaminOno multiphase solutions on the torus found by SatsumaIshimori (1979), then the resulting approximation of the quantum spectrum found by Stanley is exact after an explicit renormalization of the coefficient of dispersion predicted by AbanovWiegmann (2005).
 THURSDAY, May 12. 4:00pm in 4261
Mirjana Vuletić (UMass Boston/MIT): Free boundary Schur process
Abstract: In this talk I will present our work on the free boundary Schur process, which is a generalization of the original Schur process of Okounkov and Reshetikhin. This model after some shiftmixing is a Pfaffian process. I will introduce combinatorial random corner growth/LPP models corresponding to the free boundary Schur process and present some asymptotic results. The limiting behavior for these models is given by some new deformations of universal distributions of Schur processes. This is a joint work with D. Betea, J. Bouttier, and P. Nejjar.
