graph a b s t r a c t Let G be a graph, and k a positive integer. Let h : E(G) โ†’ [0, 1] be a function. If โˆ‘ eโˆ‹x h(e) = k holds for each x โˆˆ V (G), then we call G[F h ] a fractional k-factor of G with indicator function h where F h = {e โˆˆ E(G) : h(e) > 0}. A graph G is called a fractional (k, m)delet
