Abstract

We obtain a complete characterization of LpLqL^p-L^q Carleman estimates with weight evxe^{v\cdot x} for the polyharmonic operators. Our result extends the Carleman inequalities for the Laplacian due to Kenig--Ruiz--Sogge. Consequently, we obtain new unique continuation properties of higher order Schr\"odinger equations relaxing the integrability assumption on the solution spaces.
