Operator algebras and topological dynamics: amenability and beyond

This is a Focus Programme on operator algebras and their interplay with group actions. In this context we will be interested in amenable structures and their many incarnations, and in rigidity phenomena which typically arise as soon as one leaves the amenable setup.

Conferences and Workshops:

• 7-10 June 2021: Interactions between expanders, groups and operator algebras
  
• 28 June - 9 July 2021: Groups meet C*-algebras, in honour of Siegfried Echterhoff’s 60th birthday
• 12-16 July 2021: Cuntz semigroups Workshop
  
• 2-13 August 2021: Young Mathematicians in C*-Algebra

Geometry and PDEs: from theory to applications

This Focus Programme aims to connect the fields of differential geometry, metric geometry, PDEs, calculus of variations, data science and numerics. We will study geometric flows, geometric viewpoints on PDEs and data, as well as measure-based generalizations of geometric notions.

Conferences and Workshops:

• 1-7 August 2021: Workshop on Curvature and Global Shape
• 20-24 September 2021: Analysis on singular spaces
• 1-5 November 2021: New Trends in Geometric PDE
