### 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.

#### 22/07/2019 | Conference

### 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.

### 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.
