Title: Combinatorial Hodge theory: I

Abstract:

Hodge theory of complex projective variety recently plays a prominent role in June Huh’s solution of log concavity of chromatic polynomial of a matroid. In this talk, we will discuss basic theory of Hodge structures, as well as the Kahler package. Then we try to associate for a combinatorial object a suitable Hodge structure. Our goal is to understand how tools from algebraic geometry help to solve problems from combinatorics.
