Unique continuation for Schrödinger operators and for higher powers of the Laplacian
Izabella Łaba · Mathematical Methods in the Applied Sciences · 1988
Abstract In this paper we consider the unique continuation property for Schrödinger operators and its application for proving the non‐existence of positive eigenvalues (embedded in the continuous spectrum). We also use the estimate given by Jerison and Kenig9 to prove unique continuation for higher powers of the Laplace operator.
