Quantitative convergence of the "bulk'' free boundary in an oscillatory obstacle problem

Analysis of PDEs 2022-08-10 v1

Abstract

We consider an oscillatory obstacle problem where the coincidence set and free boundary are also highly oscillatory. We establish a rate of convergence for a regularized notion of free boundary to the free boundary of a corresponding classical obstacle problem, assuming the latter is regular. The convergence rate is linear in the minimal length scale determined by the fine properties of a corrector function.
