Weighted Mean Curvature [PDF]

open access: yesSignal Processing, 2019
In image processing tasks, spatial priors are essential for robust computations, regularization, algorithmic design and Bayesian inference. In this paper, we introduce weighted mean curvature (WMC) as a novel image prior and present an efficient ...

The mean curvature at the first singular time of the mean curvature flow [PDF]

open access: yesAnnales de l'Institut Henri Poincaré C, Analyse non linéaire, 2010
Consider a family of smooth immersions $F(\cdot,t): M^n\to \mathbb{R}^{n+1}$ of closed hypersurfaces in $\mathbb{R}^{n+1}$ moving by the mean curvature flow $\frac{\partial F(p,t)}{\partial t} = -H(p,t)\cdot \nu(p,t)$, for $t\in [0,T)$. We prove that the

Curvature estimates for surfaces with bounded mean curvature [PDF]

open access: yesTransactions of the American Mathematical Society, 2011
Estimates for the norm of the second fundamental form, $|A|$, play a crucial role in studying the geometry of surfaces. In fact, when $|A|$ is bounded the surface cannot bend too sharply.

Constant mean curvature surfaces [PDF]

open access: yesSurveys in Differential Geometry, 2016
In this article we survey recent developments in the theory of constant mean curvature surfaces in homogeneous 3-manifolds, as well as some related aspects on existence and descriptive results for $H$-laminations and CMC foliations of Riemannian $n ...

Mean curvature flow with obstacles [PDF]

open access: yesAnnales de l'Institut Henri Poincaré C, Analyse non linéaire, 2012
We consider the evolution of fronts by mean curvature in the presence of obstacles. We construct a weak solution to the flow by means of a variational method, corresponding to an implicit time-discretization scheme.

The hyperbolic mean curvature flow [PDF]

open access: yesJournal de Mathématiques Pures et Appliquées, 2007
We introduce a geometric evolution equation of hyperbolic type, which governs the evolution of a hypersurface moving in the direction of its mean curvature vector.

Weighted Ricci curvature in Riemann-Finsler geometry [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2021
Ricci curvature is one of the important geometric quantities in Riemann-Finsler geometry. Together with the $S$-curvature, one can define a weighted Ricci curvature for a pair of Finsler metric and a volume form on a manifold.

Motion by crystalline-like mean curvature: A survey

open access: yesBulletin of Mathematical Sciences, 2022
We consider a class of anisotropic curvature flows called crystalline curvature flows. We present a survey on this class of flows with special emphasis on the well-posedness of its initial value problem.
