In this paper we construct a Ricci DeTurck flow on any incomplete Riemannian manifold with bounded curvature. The central property of the flow is that it stays uniformly equivalent to the initial incomplete Riemannian metric, and in that sense preser

We consider Ricci flow starting from warped product manifolds \(\left( {\mathbb {R}}\times N, k_0 + g_0^2 g_N\right) \), whose typical fibre \((N,g_N)\) is closed and Ricci flat. Here \(k_0\) is a Riemannian metric on \({\mathbb {R}}\) and \(g_0: {\m

We consider the Ricci flow on noncompact $$n+1$$ -dimensional manifolds M with symmetries, corresponding to warped product manifolds $$\mathbb {R}\times T^n$$ with flat fibres. We show longtime existence and that the Ricci flow solution is of type II

We consider the long-time behaviour of the mean curvature flow of spacelike hypersurfaces in the Lorentzian product manifold $M\times\mathbb{R}$, where $M$ is asymptotically flat. If the initial hypersurface $F_0\subset M\times\mathbb{R}$ is uniforml

We consider convex symmetric lens-shaped networks in R 2 \mathbb {R}^2 that evolve under the curve shortening flow. We show that the enclosed convex domain shrinks to a point in finite time. Furthermore, after appropriate rescaling the evolving netwo
