Swiss Doctoral Program in Mathematics

Séminaire Kervaire 2021: Baum-Connes Conjecture

24 - 29 Octobre 2021
Les Diablerets, Switzerland

New dates: 24 - 29 Octobre 2021

Some nice snow-covered mountain

The Baum-Connes conjecture bridges Operator Algebras, Index Theory, Geometric Group Theory and Metric Geometry. It is therefore a unifying theme in Mathematics. The mini-courses will serve as an introduction to the subject, while the talks by younger experts will explain the search towards positive results and also towards counterexamples.

All talks will be given in english.


Lectures (2h each)
