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.

Fourier expansions of vector-valued automorphic functions with non-unitary twists
Ksenia Fedosova, Anke Pohl, Julie Rowlett
We provide Fourier expansions of vector-valued eigenfunctions of the hyperbolic Laplacian that are twist-periodic in a horocycle direction. The twist…
Galois cohomology and profinitely solitary Chevalley groups
Holger Kammeyer, Ryan Spitler
For every number field and every Cartan Killing type, there is an associated split simple algebraic group. We examine whether the corresponding…
Yamabe problem in the presence of singular Riemannian Foliations
Diego Corro, Juan Carlos Fernández and Raquel Perales
Using variational methods together with symmetries given by singular Riemannian foliations with positive dimensional leaves, we prove the existence of…
Initial stability estimates for Ricci flow and three dimensional Ricci-pinched manifolds
Alix Deruelle, Felix Schulze, Miles Simon
This paper investigates the question of stability for a class of Ricci flows which start at possibly non-smooth metric spaces. We show that if the…
