Non-homothetic convex ancient solutions for flows by high powers of curvature
Susanna Risa, Carlo Sinestrari
We prove the existence of closed convex ancient solutions to curvature flows which become more and more oval for large negative times. The speed function is a general symmetric fun…

Strong spherical rigidity of ancient solutions of expansive curvature flows
Susanna Risa, Carlo Sinestrari
We consider geometric flows of hypersurfaces expanding by a function of the extrinsic curvature and we show that the homothethic sphere is the unique solution of the flow which con…

Ancient solutions of geometric flows with curvature pinching
Susanna Risa, Carlo Sinestrari
We prove rigidity theorems for ancient solutions of geometric flows of immersed submanifolds. Specifically, we find pinching conditions on the second fundamental form that characte…
