Differential Geometry

Our research ranges from the general (i.e. the development of abstract frameworks to tackle the study of geometric structures) to the specific (the study of concrete geometries). In doing so, we borrow tools from Algebra, Geometric Analysis, and Homotopy Theory. Some of our research interests include:
  • Foliation Theory
  • Generalised Geometry
  • Geometry of PDEs
  • h-Principle
  • Index Theory
  • Lie Theory, including Lie algebroids and groupoids
  • Non-linear elliptic PDEs and their applications in Differential Topology
  • Poisson Geometry
  • Symplectic Geometry and Topology, Contact Topology
  • Subriemannian Geometry
Our members are part of the Dutch cluster on Geometry and Quantum Theory (GQT).

National events

Miniworkshop on Symplectic Geometry. This is a yearly event organised by O. Fabert (VU) and F. Ziltener (UU). The ninth edition took place in Utrecht in 2019.
Dutch Differential Topology and Geometry seminar. The DDT&G is a monthly seminar organised between the universities of Amsterdam, Leiden and Utrecht. It features 2-hour minicourses aimed at a broad audience of master students and researchers, and focused on exciting recent developments.

International events

The Friday Fish. Our (formerly local) seminar on Poisson Geometry, now available online.
Higher Geometric Structures along the Lower Rhine. This is a biyearly event jointly organised between the universities of Bonn, Nijmegen and Utrecht. Its focus lies on the development and application of new structures in geometry and topology. The last workshop took place in 2020.
