On local‐in‐time Strichartz estimates for the Schrödinger equation with singular potentials

There have been a lot of works concerning the Strichartz estimates for perturbed Schrödinger equation by potential. These can be basically carried out adopting well-known procedure obtaining from weighted L2 resolvent Laplacian. In this paper we handle without relying on estimates. This enables us to consider various potential classes such as Morrey–Campanato classes.
