The gauged symplectic sigma-model

Tuesday, November 15, 2016 -
1:30pm to 2:30pm
I will recall the construction of the space of states in a gauged topological A-model. Conjecturally, this gives the quantum cohomology of Fano symplectic quotients: in the toric case, this is Batyrev's presentation of quantum cohomology of toric varieties. Time permitting, I will discuss the role of "Coulomb branches" in gauge theory in relation to equivariant quantum and symplectic cohomology.
