Unique continuation for the solutions of the laplacian plus a drift
Annales de l'Institut Fourier, Tome 41 (1991) no. 3, pp. 651-663.

Nous prouvons l’unicité du prolongement pour les solutions de l’inégalité |Δu(x)|≤V(x)|∇u(x)|, x∈Ω où Ω est une partie connexe de R n et V appartient aux espaces de Morrey F α,p , avec p≥(n-2)/2(1-α) et α<1. Ces espaces contiennent L q pour q≥(3n-2)/2 (voir L. Hörmander, Comm. PDE, 8 (1983, 21-64 et Barceló, Kenig, Ruiz, Sogge, Ill. J. of Math., 32-2 (1988), 230-245).

We prove unique continuation for solutions of the inequality |Δu(x)|≤V(x)|∇u(x)|, x∈Ω a connected set contained in R n and V is in the Morrey spaces F α,p , with p≥(n-2)/2(1-α) and α<1. These spaces include L q for q≥(3n-2)/2 (see [H], [BKRS]). If p=(n-2)/2(1-α), the extra assumption of V being small enough is needed.
