Abstract: We develop a non-perturbative definition of RMT2: a generalization of random matrix theory that is compatible with the symmetries of two-dimensional conformal field theory. Given any random matrix ensemble, its n-point spectral...

The Kadomtsev-Petviashvili (KP) Equation has deep connections to algebraic curves, with solutions constructed from Riemann theta functions in the style of Krichever. As a curve undergoes tropical degeneration, its theta function simplifies to a...

This is a new era in astronomy and astrophysics on every measurable axis, where fundamental breakthroughs are being made with astonishing frequency. The entire Universe is our laboratory, and analysis of these data has transformed our understanding...

We discuss some equivariant compactifications of linear subspaces, controlled by the combinatorics of polymatroids. Open problems of interest to the Schubert calculus community will be emphasized. Joint with Colin Crowley & Botong Wang.

We will consider finite collections of squares tiles, and ask when we can tile the whole plane in an interesting way. This question is related to the algebraic structure of ‘lattices in products of trees’, which are discrete groups acting...

Suppose given a class of finite combinatorial structures, such as graphs or total orders. Nate Harman and I recently introduced a notion of measure in this context: this is a rule assigning a number to each structure such that some axioms are...
