Syllabus/achievement requirements

Recommended textbooks:

[P] G.K. Pedersen. C*-Algebras and Their Automorphism Groups.

[D] K. Davidson. C*-Algebras by Example.

 

For the exam you will need a good understanding of the following topics:

  • Different characterizations of positive elements.
  • Functional calculus of selfadjoint elements.
  • Homomorphisms, ideals, quotients, unitization, approximate units.
  • GNS-construction.
  • Irreducible representations and pure states.
  • Structure of C*-algebras of compact operators.
  • Three fundamental operator topologies.
  • Von Neumann double commutant theorem and Kaplansky density theorem.

A reasonably good understanding of the following topics:

  • Inductive limits of C*-algebras. AF-algebras. UHF-algebras.
  • Bratteli diagrams.
  • Different notions of equivalence of projections (Murray-von Neumann, unitary, homotopy). K0-group.
  • Classification of AF-algebras by K-theory.

Some understanding (at the level that you can clearly convey the main definitions) of the following topics:

  • Ultraweak and ultrastrong topologies.
  • II-1 factors and normal traces.
  • Trace preserving conditional expectations.
  • Injectivity and amenability.
  • Infinite tensor products and the hyperfinite II-1 factor.
  • Stinespring dilation.
  • Completely positive maps from and into matrix algebras.
