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 (www.arxiv.org) 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.

Monotonicity formulas for obstacle problems with Lipschitz coefficients

Matteo Focardi, Emanuele Spadaro and Maria Stella Gelli

Abstract

We prove quasi-monotonicity formulas for classical obstacle-type problems with energies being the sum of a quadratic form with Lipschitz coefficients, and a Hölder continuous linear term.

With the help of those formulas we are able to carry out the full analysis of the regularity of free-boundary points following the approaches of Caffarelli, Weiss and Monneau.
