Welcome to the C*-algebra course!
Our plan is to cover the following topics, roughly in this order:
- First examples of C*-algebras
- Commutative case
- Gelfand transform and functional calculus
- Gelfand-Naimark theorem
- Basic structure theory
- Unitization Positive elements
- Approximate units
- Ideals and homomorphisms
- Tensor products
- von Neumann algebras
- Operator topologies; von Neumann algebras
- von Neumann's double commutant theorem
- Kaplansky's density theorem
- Representation theory of operator algebras
- States; Gelfand-Naimark-Segal construction
- Irreducible representations and pure states
- Representations of algebras of compact operators; Voiculescu’s theorem
