三、摘要：

In this series of talks, some topics on projective spectrum will be introduced. Finitely generated structures are important subjects of study in various mathematical disciplines. Examples include finitely generated groups, Lie algebras and C*-algebras, etc. It is thus a fundamental question whether there exists a universal mechanism in the study of these vastly different entities. In 2009, the notion of projective spectrum for several elements (A1,…, An) in a unital Banach algebra B was defined through the multiparameter pencil A(z) = z1A1 + … + znAn; z∈Cn. This conspicuously simple definition turned out to have a surprisingly rich content. The talk will be given at 9:00-11:00, on each Monday in the spring semester of 2022.
