Combinatorics and Algebraic Topology of Configurations

Division and localization of characteristic polynomials of hyperplane arrangements

speaker: Takuro Abe (Kyoto University)

abstract: Freeness of line arrangements in the projective plane is intensively studied, and related to geometry and combinatorics of line arrangements. We will show that the freeness of line arrangements are related to Betti numbers of complexified complements, intersection points of lines and so on.
