| Abstract: |
In this talk, I will explain the reconstruction of Gromov-Witten invariants for elliptic orbifold projective lines and the Fan-Jarvis-Ruan-Witten(FJRW) invariants for elliptic singularities. The convergence of Gromov-Witten potentials and FJRW potentials are followed from the reconstruction. The Calabi-Yau to Landau-Ginzburg mirror symmetry and Landau-Ginzburg to Landau-Ginzburg mirror symmetry are verified for these cases. Using T.Milanov and Y.Ruan's construction of global B-model for elliptic singularities, we proved the Landau-Ginzburg/Calabi-Yau correspondence of all genera for elliptic orbifold projective lines. This is a joint work with M.Krawitz. The talk will be separated to two parts. In the first part, I will explain the general picture of Landau-Ginzburg/Calabi-Yau correspondence via global mirror symmetry. In the second part, I will talk about reconstructions, computations and the convergence. |
