摘要
In Li et al. (2009), proved that a 3-connected claw-free graph of order n with minimum degree delta contains a cycle of length at least min{n, 6 delta - 15}, and they conjectured that such graphs should have a cycle of length at least min{n, 9 delta - 3}. We prove that this conjecture is true with delta >= 8. (C) 2016 Elsevier B.V. All rights reserved.
