  ABSTRACT: In this paper, we consider the relationship between the binding number and the existence of fractional k-factors of graphs. The binding number of G is defined by Woodall as bind( G )=min{ | N G ( X ) | | X | :∅≠X⊆V( G ) } . It is proved that a graph G has a fractional 1-factor if bind( G )≥1 and has a fractional k-factor if bind( G )≥k− 1 k . Furthermore, it is showed that both results are best possible in some sense.
