Szemeredi(Abel奖得主)等人的成果;拥有当前w(m,n)最好下界,其相应上界是由J. Bourgain(Fields奖,邵逸夫奖, Abel奖,数学突破奖得主)获得. 有成果成为B. Bollobos (英国皇家院士)著研究生教材(GTM) Modern Graph Theory (Springer)中的定理(Ch6,Theorem 13,p193). 工作经历 1982.01-1986.08 安徽师范大学数学系 助教 1986.06-1991.08 河海大学数学系 讲师 1996.08-1997.08 美国Memphis大学 博士后 1997.09-2003.08 河海大学数学系 副教授,教授 1998.09-1999.01 香港大学 访问学者 1999.09-1999.12 香港浸会大学 访问学者 2000.09-2000.12 香港大学 访问学者 2001.11-2002.02 香港大学 访问学者 2003.09-至今 同济大学数学系 教授 2004.06-2004.09 香港大学 访问学者 2006.02-2006.05 台湾中央研究院 访问学者 2007.06-2007.09 香港大学 访问学者 2012.06-2012.09 香港大学 访问学者 获奖荣誉 部分获奖 1999年水利部优秀教师 2002年国家自然科学基金优秀项目(数学6个之一) 2004年教育部科技二等奖 2012年上海市优秀博士学位论文指导教师 2014年宝钢优秀教师奖 2014年上海市育才奖 2016年同济大学追求卓越奖(同济大学最高奖) 2017年上海市华强奖
