Description
Abstract: We provide evidence that the sphere and hemisphere partition functions of Calabi-Yau GLSMs, when evaluated in different phases, always have the same structure. The main ingredients that enter the result are Givental's I/J-functions, the Gamma class, and, in the case of the hemisphere, the Chern character of the D-brane. This is based on joint work with D. Erkinger, M. Romo, and E. Scheidegger.
