Abstract: |
I will discuss a connection between a deformation of 3d N = 4 supersymmetric sigma model and quantization of its hyperkähler target space. The deformation is constructed as an Ω-deformation of 2d B-twisted Landau-Ginzburg model with infinite-dimensional target space. Using this connection, I will present a unified point of view from which one can naturally understand two intriguing phenomena in 4d N = 2 gauge theory, one discovered by Nekrasov-Shatashvili and the other by Gaiotto-Moore-Neitzke and Ito-Okuda-Taki. |
