#### 30/09/2019 | Conference

### Buildings 2019

The Buildings conference is a conference series in its 26th year whith a focus on the geometry of spaces of non-positive curvature and in particular the geometry of and group actions on buildings.

Other topics represented in the conference are Kac-Moody geometry, non-compact type symmetric spaces, Coxeter groups, Artin groups (including braid groups) and lattices in locally compact groups. The conference aims in particular at young researchers in the area and fosters collaboration between researchers in closely related fields.

### DMV-Minisymposium Mathematical Perspectives on General Relativity

General Relativity is a beautiful physical theory which has successfully predicted many natural phenomena such as black holes and gravitational waves. Since Yvonne Choquet-Bruhat’s seminal work in the 1960’s, it has attracted the attention of mathematicians whose attention is caught by the fascinating interactions between the differential geometric setting of the theory, the partial differential Einstein equations describing the behavior of gravitational systems, and the intimate connections with mathematical and theoretical physics.

The aim of the minisymposium is to discuss recent progress in this very active subfield of geometric analysis in a way that is also inviting for young and experienced researchers from neighboring disciplines.

### Geometry and Approximation 2019

An international conference to bring together experts in various fields working on the general scheme of approximation of infinite geometric or algebraic structures by finitary objects. Cases of this general approach appear in Ramsey theory, coarse geometry, geometric group theory, the theory of operator algebras and ergodic theory.

### Geometric and analytic aspects of moduli spaces

This workshop is intended as the continuation of a series of highly successful international conferences centered around the analysis and geometry of gauge-theoretically deﬁned moduli spaces.

Gauge-theoretically deﬁned moduli spaces often exhibit interesting geometry at inﬁnity. In many interesting cases they are non-compact, carry special metrics (often hyperkähler) and limit to certain asymptotic models. Their description requires tools from geometry and global analysis.

We intend to bring together a number of internationally renowned experts as well as younger researchers in the ﬁeld.
