TITLEFeynman Rules in Gromov Witten Theory

ABSTRACT For compact Calabi Yau threefold, BCOV predicted Feynman rule that determine higher genus Gromov Witten invariants. Recently the conjecture is proved by the discovery of mixed spin p (msp) fields, using large N method. I shall introduce the setup and ideas. The first lecture will be a general talk to audiences working on different fields and the second lecture will be a technical talk for experts in enumerative geometry.
