Abstract

Let u:ΩCnCmu: \Omega \subset \mathbb C^n \to \mathbb C^m, for n2n \geq 2 and m1m \geq 1. Let 1p21 \leq p \leq 2, and 2(2n)21q<2(2n)^2 -1 \leq q < \infty such that 1p+1p=1\displaystyle \frac{1}{p} + \frac{1}{p'} = 1 and 1p1p=1q\displaystyle \frac{1}{p} - \frac{1}{p'} = \frac{1}{q}. Suppose uVu|\overline \partial u| \leq V |u|, where VLlocq(Ω)V \in L^q_{\operatorname{loc}}(\Omega). Then uu has a unique continuation property in the following sense: if uWloc1,p(Ω)u \in W^{1,p}_{\operatorname{loc}}(\Omega) and for some z0Ωz_0 \in \Omega, uLp(B(z0,r))\| u \|_{L^{p'}(B(z_0,r))} decays faster than any powers of rr as r0r \to 0, then u0u \equiv 0. The same result holds for q=q=\infty if uu is scalar-valued (m=1m=1).
