【校级学术报告】浅谈算子代数---从线性代数谈起

Huaxin Lin 林华新  (East China Normal University)

14:00-15:00, May 17, 2023   闵行校区数学楼102会议室




Abstract:

Operator Algebra is a branch of modern analysis. It uses analysis methods to study algebra objects. The main objects are operators on Hilbert spaces. The examples of current interests include C*-algebras of crossed products from a group action on a compact metric spaces. These examples study topological dynamical systems using operator algebras. Operator algebras also are now closely related to non-commutative geometry as well as number theory and wavelets. This lecture is an attempt to introduce operator algebras to undergraduate students as well as graduate students.

About the speaker:

林华新教授是国际算子代数领域的领袖之一,主要研究C*-代数及其分类。林教授在90年代解决了矩阵论中长期未决的Halmos问题,2000年以后引入并发展了在C*-代数分类中起到核心作用的迹秩理论,独立证明了迹秩有限C*-代数的分类定理,首次基于简单抽象结构给出广泛的C*-代数分类,推动了整个C*-代数理论的发展,2014年以来,与他人合作完成了C*-代数领域中著名的“Elliott纲领”。林教授是美国数学会首届会士,2005年获上海市科学技术进步一等奖,被邀请在1997年欧盟算子代数大会、2014年国际数学家大会(ICM)算子代数卫星会议上作大会报告,2015年受CBMS、AMS和NSF联合特别邀请作十场系列讲座,2018年美洲数学家大会作报告。
