Seminar by Bohan Fang: Oscillatory integrals in mirror LG models


 


Time: 15:00-17:00, Monday, November 20


Venue: Lecture Hall


Abstract: I will describe, via examples, the oscillatory and period integrals on the B-side of mirror symmetry. They correspond to Gromov-Witten primary and descendant invariants of Gamma-modified twisted Chern classes of the mirror coherent sheaves. The cycles for integration correspond to these mirror sheaves by homological mirror symmetry, and one may obtain higher genus invariants if using correct higher genus B-model integrands. I will also describe some applications to Gamma conjectures.
