Optimal Hardy-weights for elliptic operators with mixed boundary conditions

Analysis of PDEs 2021-03-26 v1

Abstract

We construct families of optimal Hardy-weights for a subcritical linear second-order elliptic operator (P,B)(P,B) with degenerate mixed boundary conditions. By an optimal Hardy-weight for a subcritical operator we mean a nonzero nonnegative weight function WW such that (PW,B)(P-W,B) is critical and null-critical with respect to WW. Our results rely on a recently developed criticality theory for positive solutions of the corresponding mixed boundary value problem.
