Hopf triangulations of spheres and equilibrium triangulations of projective spaces
Wolfgang Kühnel, Jonathan Spreer
Following work by the first author and Banchoff, we investigate triangulations of real and complex projective spaces of real and complex dimension that are adapted to the decom…

Conformally Einstein product spaces
Wolfgang Kühnel, Hans-Bert Rademacher
We study pseudo-Riemannian Einstein manifolds which are conformally equivalent with a metric product of two pseudo-Riemannian manifolds. Particularly interesting is the case where…
