    报告题目：Projective spectrum in Banach algebra

     报告摘要：This topic introduces some important notions of joint spectrum for a tuple of elements in a Banach algebra. It starts with elementaries and gradually develops into a survey of current frontiers of research. The topic is friendly to analysis, geometry and topology students and researchers. Topics include:

1.  de Rham cohomology.

2.  Koszul complex.

3.  Taylor spectrum.

4.  Multilinear functionals.

5.  Projective spectrum.

6.  Group C*-algebra.

7.  Infinite dihedral group.

8.  Koopman representation.

9.  Hermitian metric.

报告人简介：Rongwei Yang is a Professor of Mathematics at State University of New York at Albany, USA. His research interests include: multi-variable operator theory, several vomplex variables, Hermitian bundles, Kahler geometry on Stein domains, Chern-Weil homomorphism, cyclic cohomology.
