....c 3 . It is clear that any graph G needs at least Delta(G) colors for its edge coloring because edges incident to a vertex of degree Delta(G) must receive different colors. On the other hand, Vizing has proved in 1964 that any simple graph G has an edge coloring with at most Delta(G) 1 colors [Viz64]. His proof depends on two classical techniques called a fan sequence and an alternating path, and it immediately yields a polynomial time algorithm to find an edge coloring with at most Delta(G) 1 colors. It is known that the edge coloring problem, which asks to find an edge coloring of ....
....of all edges having color c is called the edge color class of c. By the definition of an edge coloring, clearly any edge color class is a matching. The following theorem is obtained by Vizing, which means that any graph G can be edge colored with Delta(G) or Delta(G) 1 colors. Theorem 2. 1 ([Viz64]) Any graph G satisfies Delta(G) G) Delta(G) 1. A total coloring of G is a mapping f : V [ E C satisfying the following three conditions (a) c) a) f(u) 6= f(v)forany two adjacent vertices u# v 2 V # (b) f(e) 6= f(e ) for any two adjacent edges e# e 2 E# and 15 (c) f(v) 6= ....

....3 distinct colors by C. Hence, no path of length 2 in G can be bicolored ; consequently, no path of length 3 is bicolored either, and C is a star coloring of G. 2 It is a well known result that any graph of maximum degree d can be properly colored with at most d 1 colors (cf. for instance [Viz64]) Since G is of maximum degree d when G is of maximum degree d, we deduce the following corollary. Corollary 3 Let G be a graph of order n and of maximum degree d. Then s (G) d 1. Now we turn to the case where d = 3, that is cubic graphs. By Corollary 3 above, we deduce that for ....
