Z-algebras from Coulomb branches

Abstract: I will explain how to obtain the Gordon-Stafford construction and some related constructions of $Z$-algebras in the literature, using certain mathematical avatars of line defects in 3d $\mathcal N$=$4$ theories. ​Time permitting, I will discuss the $K$-theoretic and elliptic cases as well.

Geometric Representation Theory conference

Series comments: Originally planned as a twinned conference held simultaneously at the Max Planck Institute in Bonn, Germany and the Perimeter Institute in Waterloo, Canada. The concept was motivated by the desire to reduce the environmental impact of conference travels. In order to view the talks, register at the website: www.mpim-bonn.mpg.de/grt2020 . The talks from previous days can be be viewed at pirsa.org/C20030 ; slides from the talks are posted here: www.dropbox.com/sh/cjzqbqn7ql8zcjv/AAANB82Hh4t5XDc5RPcZzW0Aa?dl=0
