In this article we extend an unknottedness theorem for compact self shrinkers to the mean curvature flow to shrinkers with finite topology and one asymptotically conical end, which conjecturally comprises the entire set of self shrinkers with finite topology and one end. A partial result for asymptotically cylindrical such shrinkers is also given. The mean curvature flow itself is used in the argument presented.
Abstract. In this article, we use the recently developed mean curvature flow with surgery for 2-convex hypersurfaces to prove certain isotopy existence and finally extrinsic finiteness results (in the spirit of Cheeger's finiteness theorem) for the space of 2-convex closed embedded hypersurfaces in R n+1 .
In this article we use the mean curvature flow with surgery to derive regularity estimates for the level set flow going past Brakke regularity in certain special conditions allowing for 2-convex regions of high density. We also show a stability result for the plane under the level set flow.
In this note we show that self shrinkers in R 3 are "topologically standard" in that any genus g compact self shrinker is ambiently isotopic to the standard genus g embedded surface in R 3 . As a consequence self shrinking tori are unknotted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
