人物經歷

1996年獲美國 Memphis 大學博士學位,學位論文研究Ramsey函式的漸近性。曾任教於安徽師範大學和河海大學。

研究方向

主要研究圖論中的極值問題,特別是Ramsey理論及極值圖的結構,以及相關領域如隨機圖論方法, 極值圖的代數構造方法。

主要貢獻

1.有結果成為 Bollobás 所著研究生教材 Modern Graph Theory(Springer) 中定理(Ch6,Theorem 13)。 2.關於經典 Ramsey 上界的估計被Chung和Graham等人寫入Erdos on Graphs(p13),被說成是這方面當前最好的上界。3.部分解決了Erdos的一個猜想,他曾為此猜想懸賞500美圓。論文在JCTB發表後,成為該刊當年Most downloaded articles 之一。
