TITLE | Instanton Counting on the Minimal Resolution of the A_1 Singularity |
ABSTRACT | In this talk, we consider different versions of Nekrasov partition functions.These are generating functions of integrations over moduli of framed sheaves on resolutions of the A_1 singularity. We consider two resolutions, the minimal resolution and the stacky resolution, that is, the quotient stack of the projective plane by the cyclic group of order 2. I will show functional equations between Nekrasov partition functions defined from these two resolutions. This is a kind of McKay correspondence. |
