Relative Langlands duality and Koszul duality
Alexander Braverman, Michael Finkelberg, Roman Travkin
Consider a pair of -dual hyperspherical varieties and equipped with equivariant quantizations , . Assume…
Schwartz -densities for the moduli stack of rank bundles on a curve over a local field
Alexander Braverman, David Kazhdan, Alexander Polishchuk
Let be the moduli stack of rank bundles with fixed determinant on a smooth proper curve over a local field . We show how to associate with a Schwartz -dens…
Coulomb branches of noncotangent type (with appendices by Gurbir Dhillon and Theo Johnson-Freyd)
Alexander Braverman, Gurbir Dhillon, Michael Finkelberg +2
We propose a construction of the Coulomb branch of a gauge theory corresponding to a choice of a connected reductive group and a symplectic finite-dimensio…
Coulomb branches of 3-dimensional gauge theories and related structures
Alexander Braverman, Michael Finkelberg
These are (somewhat informal) lectures notes for the CIME summer school "Geometric Representation Theory and Gauge Theory" in June 2018. In these notes we review the results and co…
Twisted zastava and -Whittaker functions
Alexander Braverman, Michael Finkelberg
In this note, we extend the results of arxiv:1111.2266 and arxiv:1203.1583 to the non simply laced case. To this end we introduce and study the twisted zastava spaces.
Gaiotto-Witten superpotential and Whittaker D-modules on monopoles
Alexander Braverman, Galyna Dobrovolska, Michael Finkelberg
Let be an almost simple simply connected group over complex numbers. For a positive element of the coroot lattice of let denote the space of based maps from the p…
