报告题目： Kadison-Singer Algebras

报 告人：葛力明，美国新罕布什大学教授、中国科学院数学研究所特聘教授。

在2004年国际数学家大会上做过45分钟报告。他用自由概率理论解决了Von Neumann 代数中的几个长期玄而未决的问题，为Von Neumann 代数的发展作出了非常大贡献。

内容简介：A new class of operator algebras is introduced and studied. They are maximal triangular algebras with an arbitrary von Neumann algebra as its diagonal subalgebra. The study of these algebras is closely related to minimal generating reflexive lattices of a von Neumann algebra. Classical manifolds such as the two-dimensional sphere can appear as those lattices.
