Welcome to SPP 2026
This is the platform of a coordinated research programme in mathematics, funded by the German Research Foundation (DFG). It comprises 33 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.

Injectivity results for coarse homology theories
Ulrich Bunke, Alexander Engel, Daniel Kasprowski, Christoph Winges
We show injectivity results for assembly maps using equivariant coarse homology theories with transfers. Our method is based on the descent principle...
Transfers in coarse homology
Ulrich Bunke, Alexander Engel, Daniel Kasprowski, Christoph Winges
We enlarge the category of bornological coarse spaces by adding transfer morphisms and introduce the notion of an equivariant coarse homology theory...
Residually finite rationally-solvable groups and virtual fibring
Dawid Kielak
We show that a finitely generated residually finite rationally solvable (or RFRS) group G is virtually fibred, in the sense that it admits a virtual...
Agrarian and $L^2$-invariants
Fabian Henneke and Dawid Kielak
We develop the theory of agrarian invariants, which are algebraic counterparts to $L^2$-invariants. Specifically, we introduce the notions of agrarian...
