In this paper, we generalize White's regularity and structure theory for mean-convex mean curvature flow to the setting with free boundary. A major new challenge in the free boundary setting is to derive an a priori bound for the ratio between the norm of the second fundamental form and the mean curvature. We establish such a bound via the maximum principle for a triple-approximation scheme, which combines ideas from Edelen, Haslhofer-Hershkovits, and Volkmann. Other important new ingredients… Expand

Mean curvature flow with generic initial data
We show that the mean curvature flow of generic closed surfaces in $\mathbb{R}^{3}$ avoids asymptotically conical and non-spherical compact singularities. We also show that the mean curvature flow ofExpand
Evolution of non-compact hypersurfaces by inverse mean curvature
We study the evolution of complete non-compact convex hypersurfaces in $\mathbb{R}^{n+1}$ by the inverse mean curvature flow. We establish the long time existence of solutions and provide theExpand

Convexity estimates for mean curvature flow with free boundary
We prove the convexity estimates of Huisken-Sinestrari for finite-time singularities of mean-convex, mean curvature flow with free boundary in a barrier $S$. Here $S$ can be any properly embedded,Expand
Mean curvature flow of mean convex hypersurfaces
In the last 15 years, White and Huisken-Sinestrari developed a far-reaching structure theory for the mean curvature flow of mean convex hypersurfaces. Their papers provide a package of estimates andExpand

We use Ilmanen’s elliptic regularization to prove that for an initially smooth mean convex hypersurface in $$\mathbf {R}^n$$Rn moving by mean curvature flow, the surface is very nearly convex in aExpand
Mean curvature flow singularities for mean convex surfaces
Abstract. We study the evolution by mean curvature of a smooth n–dimensional surface ${\cal M}\subset{\Bbb R}^{n+1}$, compact and with positive mean curvature. We first prove an estimate on theExpand
Singularities of mean convex level set flow in general ambient manifolds
We prove two new estimates for the level set flow of mean convex domains in Riemannian manifolds. Our estimates give control - exponential in time - for the infimum of the mean curvature, and theExpand
Regularity estimates for solutions to the mean curvature flow with a Neumann boundary condition
In this work we study the behaviour of compact, smooth, immersed manifolds with boundary which move under the mean curvature flow in Euclidian space. We thereby prescribe the Neumann boundaryExpand

Abstract The classical mean curvature flow of hypersurfaces with boundary satisfying a Neumann condition on an arbitrary, fixed, smooth hypersurface in Euclidean space is examined. In particular, theExpand

A possible evolution of a compact hypersurface in R by mean curvature past singularities is defined via the level set flow. In the case that the initial hypersurface has positive mean curvature, weExpand

Abstract We develop the notion of Brakke flow with free-boundary in a barrier surface. Unlike the classical free-boundary mean curvature flow, the free-boundary Brakke flow must “pop” upon tangentialExpand
