报告题目：How does the small circumference effect a graph to have Hamiltonian properties

摘要：Abstract:Many research results on circumference，most of them are related to their low pounds since this shows how closed a graph to be hamiltonian. Considering small circumference is to be a method to deal with many cases discussion. In this talk, we mainly focus on the relationship between small circumference of a graph and hamiltonian property of graphs and show how the small circumference effects a graph to have Hamiltonian properties.
