pósa-条件下的图的Z_4-连通性

Z_4-connectivity of Graphs Satisfying pósa-condition

一个满足pósa-条件且阶至少为3的简单图G是A-连通的当且仅当G≠C4,其中A是阶至少为4的阿贝尔群.

In this paper,a simple graph G satisfying pósa-condition with V（G）≥3 is A-connected if and only if G≠C4 was showed,in which A is an abelian group and C4 is a cycle of length 4.
