Chromatic Equivalence of a Family of K_4-homeomorphic Graphs
Qiu Xiao-peng · Journal of Jingmen Technical College · 2008
In the paper,the chromatic equivalence of which has girth 7 is studied from the point of view of its chromatic polynomials,four pairs of chromatically equivalent nonisomorphic K4-Homeomorphic graphs acquired.This conclusion helps to solve the problem of chromatic uniqueness of the K4-Homeomorphic graphs which has girth 7.
