Chromatic polynomials

open access: yes, 2023
This thesis studies the chromatic polynomial Z(G;q) and its generalizaton, the partition function Z(G;q,y) of the random cluster (RC) model. The main questions concern the location of the zeros of the chromatic polynomial, and the algorithmic approximation of the RC partition function.Chapter 2 studies the chromatic zeros of series-parallel graphs and ...

Chromatic polynomials [PDF]

open access: yes, 1994
In this thesis, we shall investigate chromatic polynomials of graphs, and some related polynomials. In Chapter 1, we study the chromatic polynomial written in a modified form, and use these results to characterise the chromatic polynomials of polygon trees. In Chapter 2, we consider the chromatic polynomial written as a sum of the chromatic polynomials
