Abstract: | Let G be a graph of order n, and n = Σki=1 ai be a partition of n with ai ≥ 2. In this article we show that if the minimum degree of G is at least 3k−2, then for any distinct k vertices v1,…, vk of G, the vertex set V(G) can be decomposed into k disjoint subsets A1,…, Ak so that |Ai| = ai,viisAi is an element of Ai and “the subgraph induced by Ai contains no isolated vertices” for all i, 1 ≥ i ≥ k. Here, the bound on the minimum degree is sharp. © 1997 John Wiley & Sons, Inc. |
