Higher Gromov-Witten Invariants of Calabi-Yau Threefolds

Explore the mixed-spin-p-fields method for calculating higher Gromov-Witten invariants of Calabi-Yau threefolds in this one-hour lecture. Delve into the successful application of this technique in solving the BCOV Feynman summation rule for Calabi-Yau quintics. Examine the geometric setup, including the p-fields reformulation of Gromov-Witten theory and FJRW theory, as well as the master space technique connecting GIT quotients. Discover how this method extends to other hypersurfaces in toric varieties, drawing from collaborative research with Huai-Liang Chang, Guo Shuai, Jun Li, Melissa Liu, and Yang Zhou.
