Abstract: For a complex reductive group G, its commuting stack parametrizes pairs of commuting group elements up to conjugacy. One can also interpret the commuting stack as G-local systems on a torus. I'll explain joint work with Penghui Li and Zhiwei Yun that calculates global functions on the commuting stack via mirror symmetry, in
particular Betti geometric Langland.
