Affine Yangian action on the Fock space

Representation Theory 2016-07-13 v2 Quantum Algebra

Abstract

The localized equivariant homology of the quiver variety of type AN1(1)A_{N-1}^{(1)} can be identified with the level one Fock space by assigning a normalized torus fixed point basis to certain symmetric functions, Jack(glN\mathfrak{gl}_N) symmetric functions introduced by Uglov. We show that this correspondence is compatible with actions of two algebras, the Yangian for slN\mathfrak{sl}_N and the affine Lie algebra sl^N\hat{\mathfrak{sl}}_N, on both sides. Consequently we obtain affine Yangian action on the Fock space.

v2, 46pages, several errors are corrected. In particular, a part of the defining relations of the affine Yangian was wrong in the first version
