### Geometric Singular Analysis and Mathematical Physics

During the conference at University Oldenburg we shall gather international experts as well as young researchers in the field of geometric analysis and mathematical physics with a focus on the following three mutually related topics

#### 31/07/2017 | Conference

### Analysis and Geometry on Graphs and Manifolds

The aim of this conference is to bring people together from geometry, operator theory, partial die l equations, probability and combinatorics. A particular focus lies on the connection between a discrete and a continuum viewpoint on the nature of the underlying space.

### Curvature and Global Shape

The purpose of the meeting is to study relationships between local and global invariants in Riemannian Geometry. Our intention is to bring together experts in the field as well as young mathematicians.
