报告题目:Chiral quantisation of symplectic resolution
报告摘要:For each complex reflection group G one can consider a canonical symplectic singularity M_G. In this work, motivated by the 4D/2D duality in physics (Beem et al.), we initiate a programme to study "chiral" quantisations of resolutions of singular symplectic varieties, given as Nakajima quiver varieties. We consider the special case of G=S_N acting on the affine plane. The corresponding singularity is resolved by the N-point Hilbert scheme H_N of the plane. We construct a sheaf of vertex algebras on H_N, whose global sections quantise M_{S_N}, in analogy to the quantisation result by Kashiwara and Rouquier in the "classical" setting. This is joint work with Tomoyuki Arakawa and Toshiro Kuwabara.
