Signed Chromatic Polynomials of Signed Book Graphs
Abstract
In 2015, Matthias Beck and his team developed a computer program in SAGE which efficiently determines the number of signed proper k-colorings for a given signed graph. In this article, we determine the number of different signatures on Book graph up to switching isomorphisms. We also find a recursive formula of the signed chromatic polynomials of signed Book graphs.
