Abstract

We prove a weighted fractional inequality involving the solution u of a nonlocal semilinear problem in Rn. Such inequality bounds a weighted L2-norm of a compactly supported function ϕ by a weighted Hs-norm of ϕ. In this inequality a geometric quantity related to the level sets of u will appear. As a consequence we derive some relations between the stability of u and the validity of fractional Hardy inequalities.
