摘要
本文定义了一个新的图类——K1,p-约束图,它包含了无爪图和几乎无爪图.本文证明:顶点数不小于3的连通、局部连通的K1,p-约束图是完全圈可扩的.这一结果包含了Hendry和Ryjac∨ek在无爪图和几乎无爪图上的相应结果.
In this paper,a new class of graphs is defined which contains claw free graphs and almost claw free graphs.It is called K 1,p controlled graph.The authors prove that every connected,locally connected K 1,p controlled graph on at least three vertices is fully cycle extendable.This result includes the corresponding results on claw free graphs and almost claw free graphs obtained by Hendry and Ryjác ∨ek.
