# Geometry at Infinity

Priority programme of the DFG

## 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.

#### Rectangular constrained Willmore minimizers and the Willmore conjectureLynn Heller, Sebastian Heller, Cheikh Birahim Ndiaye

We show that the well-known family of $2$-lobed Delaunay tori $\;f^b\;$ in $\;S^3,\;$ parametrized by $\;b \in \mathbb R_{\geq1},\;$ uniquely...

#### Symmetries of exotic negatively curved manifoldsMauricio Bustamante, Bena Tshishiku

Let N be a smooth manifold that is homeomorphic but not diffeomorphic to a closed hyperbolic manifold M. In this paper, we study the extent to which N...

#### Boundary maps and maximal representations on infinite dimensional Hermitian symmetric spaces Bruno Duchesne, Jean Lécureux, Maria Beatrice Pozzetti

We define a Toledo number for actions of surface groups and complex hyperbolic lattices on infinite dimensional Hermitian symmetric spaces, which...
