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

open access: yesBoundary Value Problems, 2007
We define a notion of Kato class of measures relative to a Riemannian strongly local p-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 ...

The Harnack inequality for infinity-harmonic functions [PDF]

open access: yesElectronic Journal of Differential Equations, 1995
solutions of the equation $ Delta_infty u = 0 $ is proved, extending a previous result of L.C. Evans for smooth solutions. The method of proof consists in considering $ Delta_infty u = 0 $ as the limit as $poinfty$ of the more familiar $p$-harmonic ...

Harnack inequality and no-arbitrage bounds for self-financing portfolios [PDF]

open access: yes, 2009
We give a direct proof of the Harnack inequality for a class of Kolmogorov operators associated with a linear SDE and we find the explicit expression of the optimal Harnack constant.

Harnack Inequality and Fundamental Solution for Degenerate Hypoelliptic Operators [PDF]

open access: yes, 2017
In this thesis we study subelliptic operators in divergence form on R^N, and we are interested in establishing Harnack inequalities related to these operators in various contexts.

On the parabolic Harnack inequality for non-local diffusion equations [PDF]

open access: yes, 2020
We settle the open question concerning the Harnack inequality for globally positive solutions to non-local in time diffusion equations by constructing a counter-example for dimensions d ≥ β, where β ∈ (0,2] is the order of the equation with respect to ...

On the Harnack inequality for antisymmetric $s$-harmonic functions [PDF]

open access: yes, 2023
We prove the Harnack inequality for antisymmetric $s$-harmonic functions, and more generally for solutions of fractional equations with zero-th order terms, in a general domain.

Compactness methods for Hölder estimates of certain degenerate elliptic equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper we obtain the interior $C^{1,\alpha}$ regularity of the quasilinear elliptic equations of divergence form. Our basic tools are the elementary local $L^\infty$ estimates and weak Harnack inequality for second-order linear elliptic equations,

Gradient estimates for the Fisher–KPP equation on Riemannian manifolds

open access: yesBoundary Value Problems, 2018
In this paper, we consider positive solutions to the Fisher–KPP equation on complete Riemannian manifolds. We derive the gradient estimate. Using the estimate, we get the classic Harnack inequality which extends the recent result of Cao, Liu, Pendleton ...
