Mean curvature flow and Riemannian submersions [PDF]

open access: yes, 2015
We give a sufficient condition ensuring that the mean curvature flow commutes with a Riemannian submersion and we use this result to create new examples of evolution by mean curvature flow.

On Submanifolds with Harmonic Mean Curvature [PDF]

open access: yesProceedings of the American Mathematical Society, 1995
The classification of curves in E m {E^m} with harmonic mean curvature vector field in the normal bundle is obtained and then it is used to obtain some applications.

Factorable Surfaces in Pseudo-Galilean Space with Prescribed Mean and Gaussian Curvatures

open access: yesJournal of New Theory, 2022
We study the so-called factorable surfaces in the pseudo-Galilean space, the graphs of the product of two functions of one variable. We then classify these surfaces when the mean and Gaussian curvatures are functions of one variable.

Highly Degenerate Harmonic Mean Curvature Flow [PDF]

open access: yes, 2008
We study the evolution of a weakly convex surface $\Sigma_0$ in $\R^3$ with flat sides by the Harmonic Mean Curvature flow. We establish the short time existence as well as the optimal regularity of the surface and we show that the boundaries of the flat

Heat content and mean curvature [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 1998
We use distance function methods to obtain results on the heat content of a domain in an arbitrary Riemannian manifold. In particular, we give an algorithm for the calculation of the complete asymptotic series (for small times) of the heat content of a ...

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

Constant mean curvature surfaces in AdS_3 [PDF]

open access: yes, 2010
We construct constant mean curvature surfaces of the general finite-gap type in AdS_3. The special case with zero mean curvature gives minimal surfaces relevant for the study of Wilson loops and gluon scattering amplitudes in N=4 super Yang-Mills.

Bernstein-type theorems in hypersurfaces with constant mean curvature

open access: yesAnais da Academia Brasileira de Ciências, 2000
By using the nodal domains of some natural function arising in the study of hypersurfaces with constant mean curvature we obtain some Bernstein-type theorems.

Universality in mean curvature flow neckpinches [PDF]

open access: yes, 2014
We study noncompact surfaces evolving by mean curvature flow. Without any symmetry assumptions, we prove that any solution that is $C^3$-close at some time to a standard neck will develop a neckpinch singularity in finite time, will become asymptotically

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},
