Abstract

Abstract: The paper considers the initial value problem of inhomogeneous fourth-order Schrödinger equation with potential in energy space H²(R^d). The global well-posedness is obtained in dimensions d≥5 resorting to contractive mapping principle, Strichartz estimates, Caffarelli-Kohn-Nirenberg-type inequality and the continuity method.

Key words: Well-posedness, Inhomogeneous fourth-order Schr?dinger equation, Potential; Strichartz estimates, Continuity method
