Instanton counting via affine Lie algebras II: from Whittaker vectors to the Seiberg-Witten prepotential
Alexander Braverman, Pavel Etingof
We introduce the notion of the (instanton part of the) Seiberg-Witten prepotential for general Schrodinger operators with periodic potential. In the case when the operator in quest…

Symplectic reflection algebras, Calogero-Moser space, and deformed Harish-Chandra homomorphism
Pavel Etingof, Victor Ginzburg
To any finite group G of automorphisms of a symplectic vector space V we associate a new multi-parameter deformation, H_k, of the smash product of G with the polynomial algebra on…
