... that if there are multiple edges between two vertices to use, each choice gives rise to a different spanning tree. We cannot include two parallel edges in a spanning tree as this would be a 2-cycle. We similarly never have loop edges in a spanning tree. Theorem. Let κ(G) denote the number of spannin ...
