Abstract: For compact Calabi Yau threefold, BCOV (1993) 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. A consequence is that Fg is analytic. I shall introduce the setup and ideas.
