Volume 2016/2017
Education

MSc Programme in Mathematics

Content

 

Commutative Banach algebras, C*-algebras, commutative C*-algebras, continuous function calculus, states and representations, GNS representations, polar decomposition, non-unital C*-algebras and approximate units. von Neumann algebras. The bicommutant theorem and Kaplanski's density theorem. Borel function calculus. Type decomposition of von Neumann algebras.

 

Learning Outcome

 

The participants are expected to acquire the knowledge listed above in the course description.

The participants are expected to be able to understand and apply the Gelfand transform and the GNS-construction, they must understand basic facts about order. They must have some familiarity with important examples of C*-algebras. They must understand the basics of von Neumann algebras.

The participants are expected to master the most fundamental concepts and constructions for C*-algebras and von Neumann algebras which are are used in further studies in operator algebras and in non-commutative geometry
