On the size of edge chromatic 5-critical graphs

On the size of edge chromatic 5-critical graphs

In this paper, we study the size of edge chromatic 5-critical graphs in several classes of 5-critical graphs. In most of the classes of 5-critical graphs in this paper, we have obtained their exact size and in the other classes of 5-critical graphs, we give new bounds on their number of major vertic...
