L p -inequalities for the laplacian and unique continuation
Annales de l'Institut Fourier, Volume 31 (1981) no. 3, pp. 153-168.

We prove an inequality of the type

|x|rfLp(Rn)c(n,p,q,r)|x|τ+μΔfLq(Rn).

This is then used to derive the unique continuation property for the differential inequality |Δf(x)||v(x)||f(x)| under suitable local integrability assumptions on the function v.

Nous démontrons une inégalité de la forme

|x|rfLp(Rn)c(n,p,q,r)|x|τ+μΔfLq(Rn).

Comme applications nous obtenons la propriété de prolongement unique pour l’inégalité différentielle |Δf(x)||v(x)||f(x)| si vL Loc p avec p>maxn 2 ,n-2).
