Definition1.2: A graph G is said to be L-edge colourable if there exists an L-edge colouring of G. Definition1.3: The minimum number of primary colours 'n' for which there is an L-edge colouring of G is called the L-edge chromatic number of G and is denoted by ' ( ) L G χ...
Consider the random graphG(n,p)where every two vertices in the graph are connected randomly and independently with probabilityp. DenoteG∼G(n,p)ifGis generated in this way. The chromatic numberχ(G)of a graphGmeans how many colors are needed to vertex-color it. ...
The star-chromatic number of a graph, a concept introduced by Vince, is a natural generalization of the chromatic number of a graph. We point out an alternate definition of the star-chromatic number, which sheds new light on the relation... X Zhu - John Wiley & Sons, Inc. 被引量: 32...

the case that the edge probability p is a fixed constant. For sparse random graphs much more is known. For example, Achlioptas and Naor [1] proved that for every d>0, the chromatic number of the random graph Gn,d/n is with high probability either k or k+1, where k is the ...
An upper bound for the circular game chromatic number of a graph in terms of its acyclic chromatic number is also given. We also determine the exact value of the circular game chromatic number of some special graphs, including complete graphs, paths, and cycles. In our definition of circular...

摘要: The chromatic number of the categorical product of two n-tournaments can be strictly smaller than n. We show that min{ (S T) : S and T are n-tournaments} is asymptotically equal to n , where 1 2 .DOI: 10.1090/dimacs/063/13 年份: 2001 ...
