Decay of scattering solutions to one-dimensional free Schrödinger equation

Abstract

In this paper, we investigate the decay property of scattering solutions to the initial value problem for the free Schrödinger equation in $\mathbb{R}$. It becomes clear that the rate of time decay is essentially determined by the behavior of the Fourier transform of initial data near the origin. The proof is described by basic calculus.
