A general existence proof for non-linear elliptic equations in semi-Riemannian spaces
Claus Gerhardt
We present a general existence proof for a wide class of non-linear elliptic equations which can be applied to problems with barrier conditions without specifying any assumptions g…

Curvature estimates for Weingarten hypersurfaces in Riemannian manifolds
Claus Gerhardt
We prove curvature estimates for general curvature functions. As an application we show the existence of closed, strictly convex hypersurfaces with prescribed curvature , where…

Curvature flows in semi-Riemannian manifolds
Claus Gerhardt
We prove that the limit hypersurfaces of converging curvature flows are stable, if the initial velocity has a weak sign, and give a survey of the existence and regularity results.
