spanning treeweighted graphIn this article, we extend Moon's classic formula for counting spanning trees in complete graphs containing a fixed spanning forest to complete bipartite graphs. Let (X,Y) $(X,Y)$ be the bipartition of the complete bipartite graph Km,n ${K}_{m,n}$ with ∣X...

In this paper we always take the complete graph Km for H and a certain spanning tree T for G. There are some obvious necessary conditions for a T-factorization of Km to exist. First, since the number of edges m−1 of T must divide the number of edges m(m−1)/2 of Km, obviou...
Edge-coloring Complete graph Rainbow spanning tree 1. Introduction A spanning tree T of a connected graph G is an acyclic connected subgraph of G for which V(T)=V(G). A proper k-edge-coloring of a graph G is a mapping from E(G) into a set of colors, {1,2,…,k}, such that ...

graph design. 2 Notations and De�nitions W e use the standard notation of [1 ]. Let K n denote the complete, simple graph on n v ertices. A tree T is called a line ar tr e e, if eac h v ertex of T has degree 1 or 2. The length of a line ar tr e e T = (V ...
A basic remark of Erdős and Rado states that in any coloring of the edges of a complete graph with two colors there is a monochromatic spanning tree. This remains true for G-colorings of complete graphs as proved in [1], see also [6]. Our starting point is another generalization of...
In this paper, we first determine resistance distances in the vertex-weighted complete split graph Sm,nω. Then we obtain the Moon-type formula for the vertex-weighted complete split graph Sm,nω, that is, the weighted spanning tree enumerator of Sm,nω containing any fixed spanning forest....
