Quantum periods and prepotential in SU(2) SQCD
Katsushi Ito, Shoichi Kanno, Takafumi Okubo
We study SU(2) supersymmetric QCD with massive hypermultiplets deformed in the Nekrasov-Shatashvili limit of the Omega-background. The prepotential of the low-energy e…
Extended Conformal Symmetry and Recursion Formulae for Nekrasov Partition Function
Shoichi Kanno, Yutaka Matsuo, Hong Zhang
We derive an infinite set of recursion formulae for Nekrasov instanton partition function for linear quiver U(N) supersymmetric gauge theories in 4D. They have a structure of a def…
Virasoro constraint for Nekrasov instanton partition function
Shoichi Kanno, Yutaka Matsuo, Hong Zhang
We show that Nekrasov instanton partition function for SU(N) gauge theories satisfies recursion relations in the form of U(1)+Virasoro constraints when β = 1. The constraints give…
W(1+infinity) algebra as a symmetry behind AGT relation
Shoichi Kanno, Yutaka Matsuo, Shotaro Shiba
We give some evidences which imply that W(1+infinity) algebra describes the symmetry behind AGT(-W) conjecture: a correspondence between the partition function of N=2 supersymmetri…
Analysis of correlation functions in Toda theory and AGT-W relation for SU(3) quiver
Shoichi Kanno, Yutaka Matsuo, Shotaro Shiba
We give some evidences of the AGT-W relation between SU(3) quiver gauge theories and A_2 Toda theory. In particular, we derive the explicit form of 5-point correlation functions in…
N=2 gauge theories and degenerate fields of Toda theory
Shoichi Kanno, Yutaka Matsuo, Shotaro Shiba +1
We discuss the correspondence between degenerate fields of the W_N algebra and punctures of Gaiotto's description of the Seiberg-Witten curve of N=2 superconformal gauge theories.…
