AbstractLet G be a graph of order p, let a, b, and n be nonnegative integers with 1 ≤ a < b, and let g and f be two integer-valued functions defined on V(G) such that a ≤ g(x) < f (x) ≤ b for all x ∈ V(G). A (g, f )-factor of graph G is a spanning subgraph F of G such that g(x) ≤ dF(x) ≤ f (x) for each x ∈ V(F). Then a graph G is called (g, f, n)-critical if after deleting any n vertices of G the remaining graph of G has a (g, f )-factor. The binding number bind(G) of G is the minimum value of |NG(X)|/|X| taken over all non-empty subsets X of V(G) such that NG(X) ≠ V(G). In this paper, it is proved that G is a (g, f, n)-critical graph ifFurthermore, it is shown that this result is best possible in some sense.

Let $k\geq 2$ be an integer, and let $G$ be a graph of order $n$ with $n\geq4k-5$. A graph $G$ is a fractional $k$-deleted graph if there exists a fractional $k$-factor after deleting any edge of $G$. The binding number of $G$ is defined as 26741 {\operatorname {bind}} (G)=\min\left\{\frac{|N_G(X)|}{|X|}:\emptyset\neq X\subseteq V(G),N_G(X)\neq V(G)\right\}. 26741 In this paper, it is proved that if ${\operatorname {bind}} (G)>\frac{(2k-1)(n-1)}{k(n-2)}$, then $G$ is a fractional $k$-deleted graph. Furthermore, it is shown that the result in this paper is best possible in some sense.

The binding number of a graph G is defined to be the minimum of [Formula: see text] taken over all nonempty [Formula: see text] such that [Formula: see text]. Binding number, one indicator to better understand graph, is an important characteristic quantity of a graph. In this paper, the relationships between the binding number and some other graph vulnerability parameters, namely the toughness, integrity, rupture degree and scattering number, are established. Exact values for the binding numbers of wheel related graphs namely gear, helm, sunflower and friendship graph are obtained.
