Title: Characteristic Polynomial of Hyperplane Arrangements

Abstract: The characteristic polynomial is an invariant to measure the complement of a hyperplane arrangement, whose coefficients has been well studied in the literature. A big breakthrough was obtained by J. Huh recently, who solved the Rota's conjecture on the unimodality of coefficients of characteristic polynomials, proposed 50 years ago. In this talk, we will introduce more results on the characteristic polynomial of hyperplane arrangements and its coefficients.
