Strichartz estimates for the Schrödinger propagator in Wiener amalgam spaces (1902.08940v2)

Published 24 Feb 2019 in math.AP

Abstract: In this paper we study the Strichartz estimates for the Schr\"odinger propagator in the context of Wiener amalgam spaces which, unlike the Lebesgue spaces, control the local regularity of a function and its decay at infinity separately. This separability makes it possible to perform a finer analysis of the local and global behavior of the propagator. Our results improve some of the classical ones in the case of large time.
