TITLE Coulomb branch and fixed points of 3d N=4 gauge theories
ABSTRACT I will present a new approach to study the fixed points of 3d N=4 gauge theories, based on an analysis of the Coulomb branch of vacua. The Coulomb branch is described as a complex algebraic variety, parametrized by the vevs of monopole operators and SCFT fixed points sit at singular points of the variety. I will use this framework to study the fixed points of U(N) and USp(2N) gauge theories with fundamental matter, revealing some surprising features.
