周向宇,数学家
1965年3月生于湖南郴州
2013年当选中国科学院院士
1985年本科毕业于湘潭大学数学系, 1990年在中国科学院数学所获博士学位, 1998年在俄罗斯科学院Steklov数学研究所获俄国国家科学博士学位。曾任中科院数学所所长、中国数学会副理事长。曾获国家杰出青年科学基金、求是杰出青年学者奖、陈省身数学奖、国家自然科学二等奖等。2002年在国际数学家大会上作45分钟邀请报告。
周向宇主要从事多复变领域研究。他在该领域中长期探索,创立自己的方式解决了一些困难、著名问题。周向宇解决了长期悬而未决的扩充未来光管猜想—扩充未来光锥管域是全纯域。该猜想由Bogolyubov和Wightman学派从研究量子场论及Hilbert第六问题中提出并在《数学百科全书》中列为未解决问题。周向宇的这项工作被俄国科学院院士、瑞典皇家科学院院士分别写入《二十世纪的数学大事》、《数学的发展:1950-2000》;被认为是“数学发展的亮点之一”,被作为例子说明“数学如何帮助物理获得隐藏在公理中的新知识”。 对轨道连通的一般紧李群不变域,周向宇给出了其全纯包为单叶的判别准则,解决了全纯包单叶性这一多复变基本问题。周向宇与他人合作解决了L延拓定理中的最优常数问题,作为推论解决了四十年前提出的著名的Suita猜想。

周向宇
研究员、博士生导师,1965年3月生于湖南省郴州市。
1981-1985年在湘潭大学数学系本科并获学士学位,1985-1990年在中国科学院数学研究所获硕士、博士学位。1990年起在数学研究所工作,1992年9月起任中科院数学研究所副研究员,1998年9月起任该所研究员、博士生导师。2003年2月至2012年6月担任中科院数学研究所所长,2008年1月至2011年12月任中国数学会副理事长。
曾获国家杰出青年科学基金(1998)、求是杰出青年学者奖(1998)、中国科学院自然科学奖一等奖(1999)、第八届陈省身数学奖(中国数学会)(2001),在国际著名数学中心俄罗斯科学院Steklov数学研究所获俄国国家科学博士(1998),并于2002年在国际数学家大会上作45分钟邀请报告。
现任《中国科学》、《数学学报英文版》编委。
周向宇的研究领域多复变是基础数学的核心与前沿之一, 他在该领域取得一系列成果。尤其是证明了扩充未来光管猜测,即:扩充未来光管是全纯域。
扩充未来光管猜测在前苏联编篡的《数学百科全书》大词典"量子场论"条目中及其它许多文献中被列为未解决问题。该猜测源自于量子场论,40年来一直悬而未决。美国国家科学院院士 A.S.Wightman(1962年国际数学家大会45分钟报告人)和前苏联科学院院士N.N. Bogoliubov(1958年国际数学家大会1小时报告人)的两大学派分别提出并研究了该猜测。
