    View Abstract

    A classical incidence algebra contains many important invariants throughout mathematics. In this lecture we will examine applications in number theory (Euler's phi function), geometry (Euler characteristic), and graph theory (chromatic polynomial). Then we will describe a possible generalization to higher dimensions which we call a flag incidence algebra.
