SHARP ISOLATED TOUGHNESS CONDITION FOR FRACTIONAL[a,b]-FACTOR
摘要
Abstract
In this paper,we study the relationship between the fractional[a,b]-factor and the isolated toughness.By means of the graph decomposition approach,an isolated toughness condition for a graph admits fractional[a,b]-factor is determined.The sharpness of given bound is explained by a counterexample.This result improves the original isolated toughness bound for fractional[a,b]-factors.关键词
