In this article, we study the existence of a 2-factor in a K 1,nfree graph. Sumner [J London Math Soc 13 (1976), 351-359] proved that for n ≥ 4, an (n-1)-connected K 1,n -free graph of even order has a 1-factor.

Abstract
It is proved that for every positive integers k, r and s there exists an integer n = n(k,r,s) such that every k‐connected graph of order at least n contains either an induced path of length s or a subdivision of the complete bipartite graph K~k,r~. © 2004 Wiley Periodicals, Inc.

Let \(G\) be a 3-connected \(K_{1, d}\)-free graph on \(n\) vertices. We show that \(G\) contains a 3-connected spanning subgraph of maximum degree at most \(2 d-1\). Using an earlier result of ours, we deduce that \(G\) contains a cycle of length at least \(\frac{1}{2} n^{c}\) where \(c=\left(\log
