Spanning trees with at most $5$ leaves and branch vertices in total of $K_{1, 5}$ -free graphs

Pham Hoang Ha, Nguyen Hoang Trang

In this paper, we prove that every $n$ -vertex connected $K_{1, 5}$ -free graph $G$ with $σ_{4} (G) \geq n - 1$ contains a spanning tree with at most $5$ leaves and branch vertices in total…
