Global well-posedness for higher-order Schrödinger equations in weighted $L^2$ spaces

Abstract

We obtain the global well-posedness for Schrödinger equations of higher orders in weighted $L^2$ spaces. This is based on weighted $L^2$ Strichartz estimates for the corresponding propagator with higher-order dispersion. Our method is also applied to the Airy equation which is the linear component of Korteweg-de Vries type equations.
