Möbius Functions for Real Hyperplane Arrangements

Abstract for the Combinatorics Seminar 2018 November 13

I discuss the beginnings of a theory of noncommutative Möbius functions and its connections to the structure of the algebra of faces of a hyperplane arrangement. It is to be seen as a generalization of the theory of Möbius functions for lattices, developed by Rota and his school in the 70's.

This is joint work with Swapneel Mahajan.
