NMAA07012U  Introduction to Operator Algebras (IntroOpAlg)

Volume 2013/2014
MSc Programme in Mathematics
Commutative Banach algebras, C*-algebras, commutative C*-algebras, states and representations, GNS representations, polar decomposition, non-unital C*-algebras, approximate units and the multiplier algebra. Towards the end of the course we shall discuss selected examples of interesting C*-algebras such as the Toeplitz algebra, AF-algebras, irrational rotation C*-algebras, the Cuntz algebras, group C*-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.

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