Zoom recording Abstract:The Aldous-Lyons conjecture from probability theory states that every (unimodular) infinite graph can be (Benjamini-Schramm) approximated by finite graphs. This conjecture is an analogue of other influential conjectures in mathematics concerning how well certain infinite objects can be…

The free skew field as a version of noncommutative localization of the free algebra was constructed by Amitsur and Cohn. We will call the elements of the free skew field noncommutative (nc for short) rational functions. Recently, nc rational functions…

We give an introduction to the theory of locally compact quantum groups and present an old-new construction called the Rieffel deformation, which allows constructing quantum groups from simple classical objects. If time permits, we show how to construct Levy processes,…

In many machine learning tasks, the goal is to learn an unknown function which has some known group symmetries. Equivariant machine learning algorithms exploits this by devising architectures (=function spaces) which have these symmetries by construction. Examples include convolutional neural…

(A joint work with Waltraud Lederle) In order to avoid technicalities I will focus on one specific example for a higher (-)rank lattice: the group . This group exhibits strong rigidity properties, some of which are naturally expressed in topological terms. For example,…

I will explain how the study of model theory categoricity (uniqueness) theory leads to algebraic and analytic geometry. The most recent results can be interpretedas abstract formulations of biholomorphic invariants for some classes of algebraic varieties. A zoom link for…
