A state sum for the total face color polynomial

Geometric Topology 2023-08-08 v1 Combinatorics

Abstract

The total face color polynomial is based upon the Poincar\'{e} polynomials of a family of filtered nn-color homologies. It counts the number of nn-face colorings of ribbon graphs for each positive integer nn. As such, it may be seen as a successor of the Penrose polynomial, which at n=3n=3 counts 33-edge colorings (and consequently 44-face colorings) of planar trivalent graphs. In this paper we describe a state sum formula for the polynomial. This formula unites two different perspectives about graph coloring: one based upon topological quantum field theory and the other on diagrammatic tensors.
