Abstract: The ELSV formula describes the relation between Hurwitz numbers and Hodge integrals on the moduli space of stable curves. This formula was first proved by Ekedahl, Lando, Shapiro, and Vainshtein. In this talk, I will introduce the ELSV formula and present a proof of this formula via relative virtual localization given in a paper of Ravi Vakil (arXiv:0602347v2).
