Semiprojectivity 2012 - Masterclass – University of Copenhagen

Masterclass on


The University of Copenhagen

August 27 - 31, 2012

This masterclass will introduce the participants to the topic of semiprojectivity of C*-algebras. It is primarily aimed at graduate students and postdocs.

On September 2-6 (directly after the masterclass) the department hosts a small workshop on semiprojectivity. People, for whom it is relevant, may participate in both events.

Venue and dates:

The lectures will be held at the Department of Mathematical Sciences at the University of Copenhagen, and the event is hosted by the Centre for Symmetry and Deformation . The masterclass is held from Monday, August 27 to Friday, August 31, 2012. You can find information for short term visitors including directions to the mathematics department HERE. All talks take place in Auditorium 10.



  • Definition and basic results about projectivity and semiprojectivity of C*-algebras.
  • Shape theory of C*-algebras, and connection to shape theory of spaces and notions of absolute (neighborhood) retracts.
  • Connections between semiprojectivity and classification.

Material from the lectures will be made available here.
