MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV ( that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Harnack's inequality for some nonlocal equations and application

Jerome Coville


In this paper, we establish a Harnack's inequality for positive solutions of the nonlocal inhomogeneous problem $$\int_{\Omega}J\left(\frac{x-y}{g(y)}\right)\frac{u(y)}{g^n(y)}\, dy -a(x)u,$$ where $\Omega\subset\mathbb{R}^n$ is an open set, $J$ is a probability density with compact support and $g,b$ are positive bounded functions. For some particular $a(x)$, using the Harnack's Inequality, we also construct a positive solution of the above equation.
