A New Entropy Formula and Gradient Estimates for the Linear Heat Equation on Static Manifold

open access: yesInternational Journal of Analysis and Applications, 2014
In this paper we prove a new monotonicity formula for the heat equation via a generalized family of entropy functionals. This family of entropy formulas generalizes both Perelman’s entropy for evolving metric and Ni’s entropy on static manifold.

Harnack inequality for (p,q)-Laplacian equations uniformly degenerated in a part of domain

open access: yesElectronic Journal of Differential Equations, 2018
We consider a (p,q)-Laplace equation with the exponent values p,q depending on the boundary which is divided into two parts by a hyperplane. Assuming that the equation is uniformly degenerate with respect to a small parameter in the part of domain ...

Harnack Inequality for the Schrödinger Problem Relative to Strongly Local Riemannian -Homogeneous Forms with a Potential in the Kato Class

open access: yesBoundary Value Problems, 2007
We define a notion of Kato class of measures relative to a Riemannian strongly local -homogeneous Dirichlet form and we prove a Harnack inequality (on balls that are small enough) for the positive solutions to a Schrödinger-type problem relative to

An elementary proof of the Harnack inequality for non-negative infinity-superharmonic functions

open access: yesElectronic Journal of Differential Equations, 2001
We present an elementary proof of the Harnack inequality for non-negative viscosity supersolutions of $Delta_{infty}u=0$. This was originally proven by Lindqvist and Manfredi using sequences of solutions of the $p$-Laplacian.

Spatial dynamics of a nonlocal bistable reaction diffusion equation

open access: yesElectronic Journal of Differential Equations, 2020
This article concerns a nonlocal bistable reaction-diffusion equation with an integral term. By using Leray-Schauder degree theory, the shift functions and Harnack inequality, we prove the existence of a traveling wave solution connecting 0 to an ...

On the properties of infinty-harmonic functions and an application to capacitary convex rings

open access: yesElectronic Journal of Differential Equations, 2002
We study positive $infty$-harmonic functions in bounded domains. We use the theory of viscosity solutions in this work. We prove a boundary Harnack inequality and a comparison result for such functions near a flat portion of the boundary where they ...

Harnack inequality for nondivergent elliptic operators on Riemannian manifolds

open access: yes, 2002
We consider second-order linear elliptic operators of nondivergence type which is intrinsically defined on Riemannian manifolds. Cabré proved a global Krylov-Safonov Harnack inequality under the assumption that the sectional curvature is nonnegative.
