本书特色
this book is divided into five chapters.in chapter 1,we show basic terminologies,definitions and graphic parameters.in chapter 2,we present some sufficient conditions for graphs to be(a,b,k)-critical graphs.in chapter 3,we study fractional critical graphs which are the generalizations of fractional factors in graphs.in chapter 4,we investigate all fractional(a,b,k)-critical graphs.in chapter 5,we discuss a generalization of fractional factors,i.e.,fractional id-factor-critical graphs from different perspectives.
