Generalized Bethe expansions of superconformal indices
Alejandro Cabo-Bizet, Wei Li
We show the existence of infinitely many Bethe expansions for general four dimensional superconformal theories. We then propose an analytic method to systematically obtain all the…

Categories of Line Defects and Cohomological Hall Algebras
Davide Gaiotto, Nikita Grygoryev, Wei Li
Any four-dimensional Supersymmetric Quantum Field Theory with eight supercharges can be associated to a monoidal category of BPS line defects. Any Coulomb vacuum of such a theory c…
