Strong barriers for weighted quasilinear equations (2211.12183v2)
Published 22 Nov 2022 in math.AP and math.FA
Abstract: In potential theory, use of barriers is one of the most important techniques. We construct strong barriers for weighted quasilinear elliptic operators. There are two applications: (i) solvability of Poisson-type equations with boundary singular data, and (ii) a geometric version of Hardy inequality. Our construction method can be applied to a general class of divergence form elliptic operators on domains with rough boundary.
