人物经历
现任南开大学陈省身数学研究所教授、博士生导师。1983年毕业于徐州师範学院﹔1989年获北京大学理学博士学位,1989-1991年在南京大学做博士后,1986年获南京大学理学硕士学位﹔1989年获北京大学理学博士学位后到南京大学任教,任数学系系主任。1994年2月8日访问瑞士苏黎世高工(ETH)数学研究所﹔1995年至1997年受德国洪堡基金会资助在科隆大学和慕尼黑工业大学做合作研究﹔1998年2月至8月在罗马第三大学做访问教授。1998年成为国家非线性科学攀登项目组正式成员﹔1999年获得国家杰出青年基金﹔2000年成为国家重点基础研究发展规划项目组(非线性科学)成员。
1991年起历任南京大学讲师、副教授、教授、博士生导师、长江学者、数学系主任,2016年起任南开大学陈省身数学研究所教授、博士生导师。曾在德国科隆大学和慕尼黑工大做洪堡学者;曾访问瑞士苏黎世高工(ETH)数学研究所等多所国外着名大学。在Duffing方程的稳定性,KAM理论,哈密顿偏微分方程的拟周期运动、薛丁格运算元的谱理论等方面做出了一系列深刻的工作。
2018年8月1日至8月9日,第28届国际数学家大会于在巴西里约热内卢召开,尤建功教授应邀参加第28届国际数学家大会并于2日作45分钟特邀报告,报告题目为“定量几乎可约性理论及其套用”,主要介绍尤建功教授与合作者在拟周期线性系统可约性及其在运算元谱理论中的套用方面的一些成果。这是自2002年以来,继龙以明院士、张伟平院士之后,南开学者又一次应邀在国际数学家大会上作主题报告。
国际数学家大会(International Congress of Mathematicians,简称ICM)是由国际数学联盟主办的全球性数学学术会议,是国际数学届的盛会,每四年举办一次。会议的主要内容是进行学术交流,并在开幕式上颁发菲尔兹奖(1936年起)、奈望林纳奖(1982年起)、高斯奖(2006年起)和陈省身奖(2010年起)。首届国际数学家大会于1897年在瑞士苏黎世举行,至今共举办了27届。1900年巴黎大会之后,除两次世界大战期间外,国际数学家大会从未中断,2002年在中国北京举办了第24届大会。
在每届数学家大会上,组委会都会邀请一批在相关领域做出杰出工作的着名数学家作主题报告,这标誌着数学家的工作得到了国际数学界的普遍认可和讚誉,同时,对于数学家而言,也是非常高的荣誉。
任免信息
2017年12月,当选中国民主同盟第十二届中央委员会委员。
研究方向
主要是动力系统﹐特别是Hamilton动力系统。
主要贡献
现承担国家基金委重点项目和国家重大基础研究规划项目。
研究成果主要集中在KAM理论及其在常微分方程和偏微分方程中的套用方面﹔对低维环面的KAM理论做出了重要发展﹐在第一Melnikov非共振条件下得到了不变环面的存在性﹐并用于研究了国际上非常活跃的Hamilton偏微分方程的拟周期解问题﹔研究成果否定了1994年菲尔茨奖获得者Bourgain认为KAM理论不能用于重法频率的看法﹔解决了KAM理论创始人之一Moser关于摆方程Lagrange稳定性的一个公开问题﹔受到了国际同行的重视和好评。
