ABSTRACT

The initial boundary value problem in a bounded domain with moving boundaries and nonhomogeneous boundary conditions for a higher order nonlinear Schrödinger (HNLS) equation is considered. Existence and uniqueness of global weak solutions are proved as well as the stability of the solution. Additionally, a conservative numerical method of finite differences is introduced that also verifies stability properties with respect to the L 2 $$ {L}^2 $$ -norm, and along with proving its convergence, some interesting numerical examples are shown that illustrate the behavior of the solution.
