摘要

Las Vergnas (CR Acad Sci Paris S,r A 272:1297-1300, 1971), and Broersma and Tuinstra (J Graph Theory 29:227-237, 1998) independently investigated a degree sum condition for a graph to have a spanning tree whose number of leaves is restricted. In this paper, we obtain the bipartite analogy of this result.
