New Results on Chromatic Index Critical Graphs
Wenjun Shi · Journal of Henan University · 2013
Fiorini inequality is a inequality which is given by Fiorini when he studied the chromatic index critical graphs.A lower bounder of major vertices on chromatic index critical graphs was given.In this paper,we improve the result of Fiorini and give a new lower bound on the number of major vertices on chromatic index critical graphs.
