چکیده
|
We find recursive formulae for the number of perfect matchings in a graph g by splitting g into subgraphs h and q. we use these formulas to count perfect matching of p hypercube qn. we also apply our formulas to prove that the number of perfect matching in an edge-transitive graph is pm(g) = (2q/p)pm(g{u,v}), where pm(g) denotes the number of perfect matchings in g, g{u,v} is the graph constructed from g by deleting edges with an end vertex in {u,v} and uv ∈ e(g).
