摘要
提出了邻点可区别无圈边染色的概念及其相关猜想,并证明了对于一个没有孤立边的图G,如果它的邻点可区别边染色数χ′as(G)=ε,那么存在一个常数r,如果围长g(G)≥rΔlogΔ,那么G的邻点可区别无圈边染色数至多为ε+1.
In this paper, the concept of the adjacent vertex-distinguishing acyclic edge coloring and some conjectures about it are given. If G is a simple graph with no isolated edges and the adjacent vertexdistinguishing chromatic number of G is ε, there exists r〉0, if g(G)≥r△log△, then G has (ε+ 1) adjacent vertex-distinguishing acyclic edge coloring.
