"Deformation quantization from superconformal symmetry in three dimensions"

12:00pm, RLM 8.136

Abstract: I will discuss a connection between the algebra of local operators in three-dimensional N=4 superconformal field theories and the problem of deformation quantization for hyperkahler cones. This connection leads to a number of exact results for the three-point couplings of BPS operators in these theories. I will point out some surprising mathematical consequences of this correspondence.
