Lectures on freeness of finite group actions on C*-algebras at the Shanghai Special Week on Operator Algebras, 22--26 June 2009

The links below are to (partially) corrected versions of the slides used for three talks, titled "Freeness of actions of finite groups on C*-algebras" at the Special Week on Operator Algebras, East China Normal University, Shanghai, China, 22--26 June 2009. (The schedule lists only two talks. The third one was given in the slot on Friday originally intended for Guihua Gong.)

• Lecture 1 (corrected): Slides; printable version. (The proof of the theorem about crossed products of AF algebras by actions with the Rokhlin property, toward the end, was not covered in this lecture.)
• Lecture 2 (corrected): Slides; printable version.
• Lecture 3 (with preliminary corrections): Slides; printable version. Corrections not yet made:
  • Put in the definition of the Cuntz semigroup.
  • Put in Kishimoto's coauthors, on the slide on which they are mentioned but not named.
  • Proper attribution for the version of the Rokhlin property for automorphisms.

Last significant change: 29 June 2009.
