Geometry at Infinity

This paper investigates realisations of elliptic differential operators of general order on manifolds with boundary following the approach of…

We provide Fourier expansions of vector-valued eigenfunctions of the hyperbolic Laplacian that are twist-periodic in a horocycle direction. The twist…

For every number field and every Cartan Killing type, there is an associated split simple algebraic group. We examine whether the corresponding…

Using variational methods together with symmetries given by singular Riemannian foliations with positive dimensional leaves, we prove the existence of…

We give a topological classification of Lawson's bipolar minimal surfaces corresponding to his ξ- and η-family. Therefrom we deduce upper as well as…
