| TITLE | On Algebro-geometric proof of Li-Zinger Conjecture for g=1 Gromov-Witten invariant of Quintic Calabi-Yau threefold. |
| ABSTRACT |
The Guffin-Sharpe-Witten model gives a different approach to Gromov-Witten invariant of Calabi-Yau threefold. We will introduce its application to Li-Zinger Conjecture about separation of contributions to GW invariants from different components of moduli spaces. For the case of g=1 we apply Guffin-Sharpe-Witten model to solve the separation problem. We will first briefly review Zinger's symplecto-geometric proof. After that we discuss the algebro-geometric proof under the setup of modular blowup of Hu-Li and GSW model. It is a joint work with Jun Li. |
