Interior gradient estimate for 1-D anisotropic curvature flow

Page 1 INTERIOR GRADIENT ESTIMATES FOR MEAN CURVATURE EQUATIONS

In this paper we give a simple proof for the interior gradient estimate for curvature and Hessian equations. We also derive a Liouville type result for these equations. §0. Introduction The interior gradient estimate for the prescribed mean curvature equation has been extensively studied, see [9] and the references therein. For high order mean curvature equations it has also been obtained in [1...

On Anisotropic Curvature Flow Equations

We study the anisotropic flow V = bk where b > 0. We prove that if 13 < σ ≤ 1, only type I blow up occurs and if 0 < σ < 13 Type II blow up occurs. We also establish a prior estimates and existence of stationary solutions of self-similar curves and the existence of “ Abresch-Langer” type curves.

Anisotropic and Crystalline Mean Curvature Flow

Existence and uniqueness for planar anisotropic and crystalline curvature flow

We prove short-time existence of φ-regular solutions to the planar anisotropic curvature flow, including the crystalline case, with an additional forcing term possibly unbounded and discontinuous in time, such as for instance a white noise. We also prove uniqueness of such solutions when the anisotropy is smooth and elliptic. The main tools are the use of an implicit variational scheme in order...
