摘要:Let sigma(k)(G) denote the minimum degree sum of k independent vertices of a graph G. A spanning tree with at most 3 leaves is called a spanning 3-ended tree. In this paper, we prove that for any k-connected claw-free graph G with vertical bar G vertical bar = n, if sigma(k)+3(G) >= n - k, then G contains a spanning 3 -ended tree.
