WebLemma 1 If there is no minimum spanning tree of the graph G˜, then lightest spanning tree with U vertices as leaves is not feasible Proof: Consider that no spanning tree for the graph G˜ exists. Without any loss of generality assume that there are two trees in the spanning tree forest for the graph G˜. The lightest spanning tree of G must be ... Webof edges must be different. So, let e* be the smallest cost edge in T1 that is not in T2. Deleting that edge from T1 would disconnect T1 into two components. Since T1 chose that edge, it must be the smallest cost crossing edge for those two components. But by the cut property, that edge must therefore belong to every minimum spanning tree.
