主 题:Spanning tree leaves diameter Steiner tree independent number
摘 要:Some structures of spanning trees with many or less leaves in a connected graph are *** show(1) a connected graph G has a spanning tree T with minimum leaves such that T contains a longest path,and(2) a connected graph G on n vertices contains a spanning tree T with the maximum leaves such that Δ(G) =Δ(T) and the number of leaves of T is not greater than n D(G)+1,where D(G) is the diameter of G.
