Inaugural Colloquium (13/03/2019):
Speaker: Joachim Cuntz, WWU Münster, Germany.
Title: The ring of integers and C*algebras.
Abstract: Among the most basic structures in mathematics are the sets of natural numbers and of integers with their operations of addition and multiplication. These structures give rise, in a completely natural way, to C*algebras with intriguing properties. The study of these C*algebras and in particular of their Ktheoretical invariants reveals close connections with algebraic number theory. These connections can be extended, from the usual ring of integers to rings of algebraic integers in number fields.
School I (1115/03/2019):
The aim of this school is to introduce and develop several topics around the classification of operator algebras and amenability of groups and spaces. The school will be divided into three courses:

Course I: Stefaan Vaes (KULeuven, Belgium)
Title: Type III factors, free ArakiWoods factors and their (non)classification
Abstract: The course starts with a basic introduction to von Neumann algebras of type III, the modular theory of TomitaTakesaki and Connes' classification of amenable factors. I then introduce Shlyakhtenko's free ArakiWoods factors, which are free probability analogs of the injective type III factors. I present Shlyakhtenko's classification of the almost periodic free ArakiWoods factors and the more recent non almost periodic classification results from a joint work with Houdayer and Shlyakhtenko. I will finally show that this also gives rise to unclassifiably many nonisomorphic free ArakiWoods factors (joint work with Sasyk and Törnquist). 
Course II: Tullio CeccheriniSilberstein (U. Sannio, Italy)
Title: Amenability of groups.
Abstract: In these lectures, I would like to present the notion of amenability (of discrete groups), introduced in 1929 by John von Neumann in relation to the study of the BanachTarski paradox. Since then, the notion of amenability has been extended to other different settings and nowadays plays a fundamental role in Harmonic Analysis, Functional Analysis, and Operator Algebras, in Geometric and Combinatorial Group Theory, in Ergodic Theory and Dynamical Systems, as well as in Probability, Statistical Mechanics, and Mathematical Physics. I'll present some characterizations of amenability (for discrete groups), combining methods from Functional Analysis, Combinatorics & Graph Theory, Probability & Random Walks, Combinatorial and Geometric Group Theory, and Dynamical Systems.Time permitting, I'll also discuss the notion of amenability for discrete metric spaces.PROGRAMME:
 Definitions, examples, and properties of the class of amenable groups.
 The Folner condition
 Paradoxical decompositions and the Tarski alternative theorem (including the RadoHall marriage theorem for bipartite graphs).
 The MarkovKakutani type theorem for amenable groups.
 The Kesten criterion.
 The Grigorchuk cogrowth criterion.
 The OrnsteinWeiss theorem and applications: entropies.
 Cellular automata and the Garden of Eden theorem for amenable groups.
 Amenability for discrete metric spaces.

Course III: Hannes Thiel (WWUMünster, Germany)
Title: Structure and classification of amenable C*algebras.
Abstract: A series of spectacular breakthroughs over the past three years led to the completion of the decadeslong effort to classify simple, amenable C*algebras by Ktheory. We will discuss these results and the connections to the regularity conjecture of TomsWinter on the structure of simple, amenable C*algebras. We will also study the Cuntz semigroup, which is a geometric refinement of Ktheory that has been used to obtain structure and classification results for nonsimple C*algebras.
