Abstract

AbstractLet k be a fixed integer at least 3. It is proved that every graph of order (2k − 1 − 1/k)n + O(1) contains n vertex disjoint induced subgraphs of order k such that these subgraphs are equivalent to each other and they are equivalent to one of four graphs: a clique, an independent set, a star, or the complement of a star. In particular, by substituting 3 for k, it is proved that every graph of order 14n/3 + O(1) contains n vertex disjoint induced subgraphs of order 3 such that they are equivalent to each other. © 2007 Wiley Periodicals, Inc.
