Mean Curvature Flow of Mean Convex Hypersurfaces [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2016
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 and structural results that yield a precise description of singularities and of high‐curvature regions in a mean convex flow.In the present paper, we give a ...

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.

Offset Ruled Surface in Euclidean Space with Density

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
In this paper, offset ruled surfaces in these spaces are defined by using the geometry of ruled surfaces in Euclidean space with density. The mean curvature and Gaussian curvature of these surfaces are studied.

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.

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 ...

On Curvature Pinching for Submanifolds with Parallel Normalized Mean Curvature Vector

open access: yesMathematics
In this note, we investigate the pinching problem for oriented compact submanifolds of dimension n with parallel normalized mean curvature vector in a space form Fn+p(c).

The Weighted Mean Curvature Derivative of a Space-Filling Diagram

open access: yesComputational and Mathematical Biophysics, 2020
Representing an atom by a solid sphere in 3-dimensional Euclidean space, we get the space-filling diagram of a molecule by taking the union. Molecular dynamics simulates its motion subject to bonds and other forces, including the solvation free energy ...

Mean Curvature in the Light of Scalar Curvature [PDF]

open access: yesAnnales de l'Institut Fourier, 2020
We formulate several conjectures on mean convex domains in the Euclidean spaces, as well as in more general spaces with lower bounds on their scalar curvatures, and prove a few theorems motivating these ...

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.

Graphs with constant mean curvature in the 3-hyperbolic space

open access: yesAnais da Academia Brasileira de Ciências, 2002
In this work we will deal with disc type surfaces of constant mean curvature in the three dimensional hyperbolic space which are given as graphs of smooth functions over planar domains.
