Welcome to SPP 2026
This is the platform of a coordinated research programme in mathematics, funded by the German Research Foundation (DFG). It comprises 80 research projects in the fields of differential geometry, geometric topology, and global analysis. More than 80 researchers from doctoral to professorial level and based at more than 20 German and Swiss universities are represented in this programme.

Quasi-morphisms on surface diffeomorphism groups
Jonathan Bowden, Sebastian Hensel and Richard Webb
We show that the identity component of the group of diffeomorphisms of a closed oriented surface of positive genus admits many unbounded…
Local Flexibility for Open Partial Differential Relations
Christian Bär, Bernhard Hanke
We show that local deformations, near closed subsets, of solutions to open partial differential relations can be extended to global deformations,…
Bounded subgroups of relatively finitely presented groups
Eduard Schesler
Given a finitely generated group $G$ that is relatively finitely presented with respect to a collection of peripheral subgroups, we prove that every…
Stability of the Non-Symmetric Space E7/PSO(8)
Paul Schwahn, Uwe Semmelmann, Gregor Weingart
We prove that the normal metric on the homogeneous space E7/PSO(8) is stable
with respect to the Einstein-Hilbert action, thereby exhibiting the…
