Title
Spanning Trees With Small Diameters
Abstract
A spanning tree with small diameter of a graph has many applications. In this paper we first make the following conjecture and show that the condition is best possible if it is true. If a connected graph G satisfies delta (G)>= 3|G|/(d+2), then G has a spanning tree with diameter at most d, where d >= 4 is an integer. We next prove that the conjecture holds if d >= 4 is even or d is an element of {5,7,9}. Moreover, we prove that if d >= 5 is odd and delta (G)>= 3|G|/(d+1), then G has a spanning tree with diameter at most d.
