摘要
We attach topological concepts to a simple graph by means of the simplicial complex of its complete subgraphs. Using Forman%26apos;s discrete Morse theory we show that the strong product of two graphs is homotopic to the topological product of the spaces of their complexes. As a consequence, we enlarge the class of clique divergent graphs known to be homotopy equivalent to all its iterated clique graphs.
