Abstract | Given a graph G and two functions f and g: V(G) --> Z(+) with f(v)greater than or equal to g(v) for each v is an element of V(G), a (g, f)-quasifactor in G is a subgraph e of G such that for each Vertex v in V(Q), g(v)less than or equal tod(Q)(v)less than or equal to f(v); in the particular case when For Allv is an element of V(Q), f(v) = g(v) = k is an element of N, we say that Q is a k-quasifactor. A subset S of Vertices of G is said (g,f)-quasifactorable in G if there exists some (g, f)-quasifactor that contains all the vertices of S. In this paper, we give several results on the 2-quasifactorability of a vertex subset which are related to minimum degree, degree sum, independence number and neighborhood union conditions.
