| Place: | Seminar Room A |
| Abstract: | I will describe a construction from my recent preprint with the same title which assigns elliptic genus to Witten's phases of N=2 theories which include the elliptic genus of Landau-Ginzburg models associated with weighted homogeneous polynomials, elliptic genus of Calabi-Yau manifolds and elliptic genus of hybrid models. In particular, using this construction one can derive LG/CY correspondence for elliptic genus from McKay correspondence. In the final part of the talk I discuss a recent paper with L. Borisov on Pfaffian-Grassmannian double mirrors. |
