Wave jumps described by the modified Schrödinger equation (Q1571216)

The general principles of the analysis of jumps in nondissipative models are considered. The emphasis is placed on the jumps described by the Schrödinger equation with the third-order highest derivative. It is shown that the boundary conditions on the jumps can be deduced from three conservation laws. A numerical method is developed to study the jumps. The problems of wave-wall interaction and wave emission into space are solved by this method.
