#### 25/02/2019 | Conference

### Geometric Analysis meets Geometric Topology

The goal of the conference is to bring together researchers in Geometric Analysis and Geometric Topology. We will also have an informal panel discussions about academic job markets in Europe and a meeting and discussion with an expert on impostor syndrome.

The conference is funded by the Gender Equality funds of the SPP Geometry at Infinity and our speakers are all women. Everyone is welcome to participate.

### Augsburg-Fribourg-Karlsruhe Riemannian Topology Meeting

The Riemannian Topology Meeting (RTM) is an irregularly recurring activity addressing mathematicians interested in the interplay of algebraic and geometric topology with riemannian geometry. Its tradition reaches back to 2012 during which it took place at the universites of Fribourg, Karlsruhe and Göttingen.

This RTM, taking place at the University of Fribourg, focuses on fostering the mathematical intercommunication between the research groups in Augsburg, Fribourg and Karlsruhe, which are participating in the SPP 2026 DFG project.
