We also propose new existence and uniqueness problems for closed self-shrinkers with bi-rotational symmetry and provide numerical evidence for the existence of new examples.</description><category>Mean curvature flow</category><category>Self-shrinkers &amp; translators</category><category>Stability &amp; uniqueness</category><category>Rotational symmetry &amp; warped products</category><category>Numerics &amp; visualization</category></item>

First, we prove Alexandrov type results for closed embedded hypersurfaces with radially symmetric higher order mean curvature in a large class of Riemannian warped product manifolds, including the Schwarzschild and Reissner-Nordström spaces, where the Alexandrov reflection principle is not available. Second, we prove that, in Euclidean space, the only closed immersed self-expanding solitons to the weighted generalized inverse curvature flow of codimension one are round hyperspheres.</description><category>Other curvature flows</category><category>Inverse mean curvature flow</category><category>Ricci solitons</category><category>Self-shrinkers &amp; translators</category><category>Stability &amp; uniqueness</category><category>Rotational symmetry &amp; warped products</category></item>
