Hello

I'm running the Polymorphisms and Constraints learning seminar again this year. The notes for the seminar are here. To join the mailing list, click here.

Notes on the sum product theorem

Some cross ratios (written for high school students)

Current draft of notes about Weil conjectures

Inequality handout from a Stanford Math Circle talk

How to include source code with an arxiv submission

Things I have written which are on the arxiv:

Sums of seven octahedral numbers (published in Journal of the London Math Society, Volume 93, Issue 1)

General divisor function inequalities and the third cumulant

Examples, counterexamples, and structure in bounded width algebras

Note on chromatic numbers of directed hypergraphs with no bad cycles

Inequalities and higher order convexity (old, never published)

Things I've written which are not yet on the arxiv:

Rough draft of a paper about binary minimal clones

Mostly finished article on a model sifting problem of Selberg

Rough draft of a paper on a semidefinite framework for sieve theory

Very very rough draft of a paper on optimal iteration rules

Slides:

A talk about sifting iterations from the 2017 JMM

A talk about spirals from the AAA94/NSAC 2017 conference

A talk about minimal clones from AAA96
