String Theory seminar - Stefano Cremonesi Seminar

Abstract: 3d N=4 gauge theories are lower-dimensional cousins of 4d N=2 gauge theories, whose low energy physics on the Coulomb branch of the moduli space of vacua was famously determined in 1994 by Seiberg and Witten. Until a few years ago, much less was known about the physics and mathematics of their three-dimensional counterparts. In this talk I will give a biased overview of results on Coulomb branches of 3d N=4 gauge theories which have been obtained in recent years, and explain some of their uses within and beyond the realm of three-dimensional physics.
