Gauge Fields in Arithmetic, Topology & Physics workshop

Arithmetic, Algebra, and Algorithms

Reflection arrangements appear in various areas of mathematics including algebra, combinatorics, differential geometry, integrability and singularity theory. The concrete research strands within these areas that we plan to focus on include Cherednik algebras, Coxeter-Catalan combinatorics, logarithmic vector fields, Frobenius manifolds and flat invariants. The main goals of the workshop are to bring together specialists from these diverse fields, to explore remarkable connections between these areas, to enhance viewpoints and to stimulate further research.

The past several years have seen landmark progress in the interplay between representation theory, geometry and mathematical physics.  Particularly notable have been Braverman, Finkelberg and Nakajima's definition of the Coulomb branch of an N=4 supersymmetric (SUSY) 3d gauge theory, and Mellit's proof of the Hausel-Letellier-Rodriguez-Villegas conjecture on the Poincare polynomials of character varieties.  The area has also seen exciting connections to other fields, such as significant progress on the conjectures of Gorsky, Negut and Rasmussen relating coherent sheaves on Hilbert schemes to Khovanov-Rozansky homology. The goal of this conference is to push forward research in areas at the nexus between these results:  affine Springer theory, double affine Hecke algebras and Coulomb branches, creating new connections between experts, and exposing young mathematicians to this fast-progressing and exciting research area.
