Abstract

This paper is the first attempt to give a rigorous mathematical study of Neumann initial boundary value problems for the multidimensional dispersive evolution equations considering as example famous nonlinear Schrödinger equation. We consider the inhomogeneous initial-boundary value problem for the nonlinear Schrödinger equation, formulated on upper right-quarter plane with initial data u(x, t) |t == u(x) and Neumann boundary data ux1|∂1D=h1(x2,t),ux2|∂2D=h2(x1,t) given in a suitable weighted Lebesgue spaces. We are interested in the study of the influence of the Neumann boundary data on the asymptotic behavior of solutions for large time. We show that problem admits global solutions whose long-time behavior essentially depends on the boundary data. To get a nonlinear theory for the multidimensional model. we propose general method based on Riemann–Hilbert approach and theory Cauchy type integral equations. The advantage of this method is that it can also be applied to non-integrable equations with general inhomogeneous boundary data.
