Homomorphisms of Trees into a Path
Let hom(G,H) denote the number of homomorphisms from a graph G to a graph H. In this paper we study the number of homomorphisms of trees into a path, and prove that hom(P[subscript m],P[subscript n]) ≤ hom(T[subscript m],P[subscript n]) ≤ hom(S[subscript m],P[subscript n]), where T[subscript m] is a...
