Breaking symmetries for equivariant coarse homology theories

Ulrich Bunke, Matthias Ludewig

We describe a symmetry breaking construction in coarse geometry which allows to obtain information about equivariant coarse homology classes by restriction to smaller groups and sp…

2-vector bundles

Peter Kristel, Matthias Ludewig, Konrad Waldorf

We develop a ready-to-use comprehensive theory for (super) 2-vector bundles over smooth manifolds. It is based on the bicategory of (super) algebras, bimodules, and intertwiners as…
