Abstract:
I will talk about conjectural dualities for the moduli of Higgs bundles on a smooth projective complex curve for Langlands dual groups. These dualities are stated using BPS cohomology and quasi-BPS categories, which are refinements of the BPS invariants of interest in enumerative geometry. I will focus on explicit computations involving semistable GL(2)-Higgs bundles. The talk is based on joint work with Chenjing Bu, Ben Davison, Andrés Ibáñez-Núñez, and Tasuki Kinko, and with Yukinobu Toda.
