报告人简介:

        龚贵华教授是国际著名算子代数与非交换几何专家,现为美国波多黎哥大学教授,国家杰青B类(2006年)获得者,河北师范大学特聘教授。主要研究方向为 C*-代数、复几何,在C*-代数的分类、强Novikov猜想和粗几何Novikov猜想等问题上做出了杰出的工作,其研究成果发表在《Annals of   Mathematics, Inventiones   Mathematicae》、《J. Reine   Angew. Math.》等国际顶级数学期刊上。他曾获2000Israel   Halperin奖,此奖为加拿大五年一度(有时空缺)的算子代数杰出成就奖。

 

报告内容:

A C-algebra A is said to have the ideal property if each closed two-sided ideal of A is generated as a closed two-sided ideal by the projections inside the ideal. C-algebras with the ideal property are a generalization and unification of real rank zero C-algebras and unital simple C-algebras. We show that a certain new algebraic K1-invariant becomes the complete invariant for AH algebras (of no dimension growth) with the ideal property.
