Ricci de Turck flow on incomplete manifolds
Tobias Marxen, Boris Vertman
In this paper we construct a Ricci de Turck flow on any incomplete Riemannian manifold with bounded curvature. The central property of the flow is that it stays uniformly equivalen…

Bounded Ricci Curvature and Positive Scalar Curvature under Singular Ricci de Turck Flow
Klaus Kroencke, Tobias Marxen, Boris Vertman
In this paper we consider a Ricci de Turck flow of spaces with isolated conical singularities, which preserves the conical structure along the flow. We establish that a given initi…

Mean curvature flow in asymptotically flat product spacetimes
Klaus Kroencke, Oliver Lindblad Petersen, Felix Lubbe +6
We consider the long-time behaviour of the mean curvature flow of spacelike hypersurfaces in the Lorentzian product manifold , where is asymptotically flat.…
