Let G be a graph and n be a positive integer. A spanning subgraph F of G is called a {1, 3, …, 2n-1} -factor if d_F(x)∈{1, 3, …, 2n-1} for all x∈ V(G). Here we give several results on {1, 3, …, 2n-1} -factors, which are the extensions of some theorems on 1-factors given by Las Vergnas, Sumner and others.
