Strong Unique Continuation for Fractional Schrödinger Operators

Abstract

We prove the strong unique continuation property for the fractional Schrödinger equation \[ (-Δ)^s u=Vu \] with scaling-critical potentials $V\in L_{\mathrm{loc}}^{\frac{n}{2s}}$ for all $0<s<1$. Our result constitutes the nonlocal counterpart to the classical Jerison--Kenig result for Schrödinger operators.
