Masterclass on Sofic groups and applications to operator algebras

The University of Copenhagen

November 5-9, 2012

 

The masterclass is aimed at PhD students and postdocs. The lectures will be self contained, and no prior knowledge on Sofic groups will be assumed. There will be three lecture series as well as some more specialized talks.

Notes, references and further reading:

Speakers:

The lecture series will be delivered by:

In addition there will be lectures by

  • Gabor Elek, Ecole Polytechnique Federale de Lausanne.
  • Eberhard Kirchberg, Humboldt-Universität zu Berlin.
  • Nicolas Monod, Ecole Polytechnique Federale de Lausanne.

Venue:

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. You can find information for short term visitors including directions to the mathematics department HERE. Note added to the visitors guide: Bus 43 is discontinued and bus 42 does not stop at the university any more.

Accommodation:

We recommend Hotel de 9 Små Hjem, which is pleasant and inexpensive and offers room with a kitchen. Other inexpensive alternatives are CabInn that has several locations in Copenhagen: the Hotel City (close to Tivoli), Hotel Scandivania (Frederiksberg, close to the lakes), and Hotel Express (Frederiksberg) are the most convenient locations; the latter two are 2.5-3 km from the math department.

Somewhat more expensive - and still recommended - options are Hotel Nora and Ibsen's Hotel. You can also check this almost up to date hotel list. Invited speakers need not reserve hotel rooms (this will be taken care of by the organizers). 

Support:

Deadline for applying for support has passed. Participants can apply for support to partly cover their living costs while attending the masterclass. The support will be DKK 500 per day, and it will primarily be given to participating PhD students and postdocs. Please indicate on the registration form if you wish to be considered for this support. If you wish to be considered for support, then you must send your cv and a brief motivation for your participation in the masterclass to Uffe Haagerup (Email: haagerup@math.ku.dk).
