Towards a mathematical definition of Coulomb branches of gauge theories

Representation Theory

19 March 15:30 - 16:30

Hiraku Nakajima - Kyoto University

Suppose a pair of a compact Lie group G and its quaternionic representation M is given. Physicists associate a hyper-Kaehler manifold, called the Coulomb branch, to (G,M). I will explain my proposal for a mathematically rigorous definition of its coordinate ring, based on the affine Grassmannian of G. This is a joint work with A.Braverman and M.Finkelberg.
