### 2nd Marburger Arbeitsgemeinschaft: The toral rank conjecture

This is the 2nd Marburger Arbeitsgemeinschaft Mathematik, each of which is devoted to an important unsolved question in pure mathematics, with the aim of giving the participants a complete picture of its state of the art. The topic of this Arbeitsgemeinschaft is the toral rank conjecture, which was formulated by Steven Halperin in 1985 and is one of the most prominent open problems in transformation groups.

### Workshop on Finiteness properties

Our goal is to bring together experts on finiteness properties of groups and spaces with young reasearchers in related areas. We expect that this will lead to new connections and interactions and introduce new people to the field. To achieve this, our workshop will offer an attractive mix of minicourses and research talks.

### Higgs bundles at infinity

The workshop is the first of a series of meetings for researchers in the field of Higgs bundles. It is intended to integrate young scientists and to give them the opportunity to present their work and to establish new contacts. Applications for financial support for young participants are open until November 22nd.
