摘要
Abstract
A graph G is a P3-dominated graph if J(x,y) UJ'(x,y)≠φ for any pair of vertices x and y of d(x,y) =2. This paper proves that for any pair of non-adjacent vertices x and y in G,which is a 2.-connected P3-dominated graph of order n no less than 3, if 2|N(x)UN(y)|+d(x)+d(y)≥2n-5, then G has a Hamilton cycle or G∈{K2,3,K1,1,3}.关键词
