W e define a partial ordering on the set of a-polynomials as well as a vertex splitting operation on the set of graphs, and introduce the notions of (r-equivalence and (r- uniqueness of graphs. Let a ( G ) be the a-polynomial of a graph G and a ( G ) = (r(GC). Let H = (G, u , A, 5) be a vertex spli
