Quaternionic-Kähler manifolds with ends of finite volume

Résumé / Abstract: I will explain a construction of complete quaternionic-Kähler manifolds with interesting fundamental groups, which are not locally symmetric. The examples include manifolds which are diffeomorphic to a cylinder over a compact locally homogeneous manifold such that one of the two ends is of finite volume. This is joint work with Danu Thung and Markus Röser, see arXiv:2105.00727.
