【Abstract】 In this survey the rational side of graph theory is revealed. Integer-based definitions and invariants are converted into their fractional analogues. Some results on fractional factors and fractional Hamilton graphs are introduced. In particular, some new results related to fractional (g,f)-factors obtained by authors are given. Furthermore, some open problems are presented.更多还原
