报告摘要:In this talk, we will give an introduction to a conjecture of Woodall in 1975which was listed as one unsolved problem in the appendix of the classical text book ``Graph Theory with Applications by Bondy and Murty in 1976. This conjecture states that every 2-connected graph on n vertices has a cycle of length at least 2k if it has at least n/2+k vertices of degree at least k. This is joint work with Binlong Li.
