Masterclass: Continuous K-theory, dualizable and rigid categories

University of Copenhagen
10-14 June, 2024

The masterclass aims to introduce the participants to new methods in, and applications of algebraic K-theory, based on Efimov's recent breakthroughs about dualizable categories and localizing motives. The masterclass will consist of three lecture series by Dustin Clausen, Alexander Efimov and Thomas Nikolaus, shedding light on different aspects of continuous K-theory, dualizable and rigid categories. This will be accompanied by informal discussion sessions in which the participants can discuss the material and exchange ideas.

Limited financial support will be available for some participants.

To appear.
















We kindly ask the participants to arrange their own accommodation.

We recommend Hotel 9 Små Hjem, which is pleasant and inexpensive and offers rooms with a kitchen. Other inexpensive alternatives are CabInn, which has several locations in Copenhagen: the Hotel City (close to Tivoli), Hotel Scandinavia (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.

An additional option is to combine a stay at the CabInn Metro Hotel with a pass for Copenhagen public transportation (efficient and reliable). See information about tickets & prices.













Register here before 31/05/2024.

A limited number of funding is available for participants. The deadline for applying for funding is 14/04/2024. If you apply for financial support, you will get further information later on.
