Abstract:
A combinatorial reciprocity theorem relates two classes of combinatorial objects via their counting functions. We shall explore the chromatic polynomial, which counts the number of proper n-colourings of a graph, and the significance of its valuation at the negative integers. Furthermore, with assistance of order polynomials and Ehrhart polynomials, a geometric interpretation of this significance will be shown.
