Quantization of hyperkahler cones and superconformal symmetry in three dimensions
I will describe a connection between the algebra of local operators in threedimensional N=4 superconformal field theories and the problem of deformation quantization for hyperkahler cones. I will point out some apparently surprising mathematical consequences of this correspondence.
Roman Bezrukavnikov, Massachusetts Institute of Technology
Coherent sheaves on symplectic resolutions and highest weight categories
I will discuss some features of the derived categories of coherent sheaves on a symplectic resolution of singularities that become manifest once the variety is reduced to positive characteristic and quantized. I will emphasize the features that are relevant to (either classical or 3D) mirror symmetry.
Alexander Braverman, Perimeter Institute & University of Toronto
Cyclotomic Cherednik algebras and quantized Coulomb branches
This talk will be devoted to the discussion of quantized Coulomb branches of 3d N=4 guage theories(as was defined mathematically in the work of Finkelberg, Nakajima and the presenter) in the case of quiver gauge theories attached to the Jordan quiver. I will show that the resulting noncommutative algebra is the spherical subalgebra in the cyclotomic Cherednik algebra.
