About me


I am a third-year graduate student in mathematics at MIT studying geometric representation theory. My advisor is Roman Bezrukavnikov.

Research

Equivariant coherent sheaves on the exotic nilpotent cone, (preprint). (arXiv)
Let G be the symplectic group, and consider Kato's exotic nilpotent cone. Following techniques used by Bezrukavnikov to establish a bijection between the dominant weights for a simple algebraic group, and O, the set of pairs consisting of a nilpotent orbit and a finite-dimensional irreducible representation of the isotropy group of the orbit, we prove an analogous statement for the exotic nilpotent cone. In order to this, we construct a quasi-exceptional set generating the bounded derived category of equivariant coherent sheaves on the exotic nilpotent cone, such that the resulting t-structure coincides with the perverse coherent t-structure.
