Geometric Inequalities for a Submanifold Equipped with Distributions

open access: yesMathematics, 2022
The article introduces invariants of a Riemannian manifold related to the mutual curvature of several pairwise orthogonal subspaces of a tangent bundle. In the case of one-dimensional subspaces, this curvature is equal to half the scalar curvature of the

Remarks on mean curvature flow solitons in warped products [PDF]

open access: yesDiscrete and Continuous Dynamical Systems. Series A, 2018
We study some properties of mean curvature flow solitons in general Riemannian manifolds and in warped products, with emphasis on constant curvature and Schwarzschild type spaces.

The mean curvature measure

open access: yesJournal of the European Mathematical Society, 2012
We assign a measure to an upper semicontinuous function which is subharmonic with respect to the mean curvature operator, so that it agrees with the mean curvature of its graph when the function is smooth. We prove that the measure is weakly continuous with respect to almost everywhere convergence.

The space of asymptotically conical self-expanders of mean curvature flow [PDF]

open access: yesMathematische Annalen, 2017
We show that the space of asymptotically conical self-expanders of the mean curvature flow is a smooth Banach manifold. An immediate consequence is that non-degenerate self-expanders—that is, those self-expanders that admit no non-trivial normal Jacobi ...

Nonlocal diffusion of smooth sets

open access: yesMathematics in Engineering, 2022
We consider normal velocity of smooth sets evolving by the $ s- $fractional diffusion. We prove that for small time, the normal velocity of such sets is nearly proportional to the mean curvature of the boundary of the initial set for $ s\in [\frac{1}{2},

New Constant Mean Curvature Surfaces [PDF]

open access: yesExperimental Mathematics, 2000
We use the Dorfmeister–Pedit–Wu construction to present three new classesof immersed CMC cylinders, each of which includes surfaces with umbilics. The first class consists of cylinders with one end asymptotic to a Delaunay surface. The second class presents surfaces with a closed planar geodesic.

Existence and uniqueness for anisotropic and crystalline mean curvature flows [PDF]

open access: yesJournal of The American Mathematical Society, 2017
An existence and uniqueness result, up to fattening, for crystalline mean curvature flows with forcing and arbitrary (convex) mobilities, is proven. This is achieved by introducing a new notion of solution to the corresponding level set formulation. Such

A remark on soliton equation of mean curvature flow

open access: yesAnais da Academia Brasileira de Ciências, 2004
In this note, we consider self-similar immersions of the mean curvature flow and show that a graph solution of the soliton equation, provided it has bounded derivative, converges smoothly to a function which has some special properties (see Theorem 1.1 ...

Constant mean curvature spheres in homogeneous three-manifolds [PDF]

open access: yesInventiones Mathematicae, 2017
We prove that two spheres of the same constant mean curvature in an arbitrary homogeneous three-manifold only differ by an ambient isometry, and we determine the values of the mean curvature for which such spheres exist.

Uniformly Compressing Mean Curvature Flow [PDF]

open access: yesThe Journal of Geometric Analysis, 2018
Michor and Mumford showed that the mean curvature flow is a gradient flow on a Riemannian structure with a degenerate geodesic distance. It is also known to destroy the uniform density of gridpoints on the evolving surfaces. We introduce a related geometric flow which is free of these drawbacks.
