%0 Journal Article %T On an initial-boundary value problem for the nonlinear Schr dinger equation %A Herbert Gajewski %J International Journal of Mathematics and Mathematical Sciences %D 1979 %I Hindawi Publishing Corporation %R 10.1155/s0161171279000405 %X We study an initial-boundary value problem for the nonlinear Schr dinger equation, a simple mathematical model for the interaction between electromagnetic waves and a plasma layer. We prove a global existence and uniqueness theorem and establish a Galerkin method for solving numerically the problem. %K conserved integrals %K a priori estimates %K unique global solution %K convergence of Fourier's method. %U http://dx.doi.org/10.1155/S0161171279000405
