On pp-waves with lightlike parallel spinors
Bernd Ammann, Jonathan Glöckle, Klaus Kroencke
We parametrize pp-wave spacetimes with compact codimension 2 hypersurfaces. In the vacuum case, we show that these spacetimes are locally in one-to-one correspondence with smooth c…

Analysis and boundary value problems on singular domains: an approach via bounded geometry
Bernd Ammann, Nadine Grosse, Victor Nistor
We prove well-posedness and regularity results for elliptic boundary value problems on certain domains with a smooth set of singular points. Our class of domains contains the class…

-spectrum of the Dirac operator on products with hyperbolic spaces
Bernd Ammann, Nadine Große
We study the -spectrum of the Dirac operator on complete manifolds. One of the main questions in this context is whether this spectrum depends on . As a first example where…
