Research Focus Geometry, Groups and Topology

The investigation of the interactions of geometric, topological and algebraic structures has reiteratively led to new scientific advances within and beyond the realms of mathematics. A preeminent example being the geometrization of 3-manifolds.

Researchers from algebraic geometry, differential geometry, geometric analysis, geometric group theory, metric geometry, topology and number theory jointly constitute the research focus "Geometry, Groups and Topology". Their objective is to represent those interactions in both research and teaching.
