Compacton-like solutions for modified KdV and nonlinear Schr??dinger equation with external sources

摘要

We present new types of compacton-like solutions for modified KdV and nonlinear Schr??dinger equation with external sources, using a recently developed fractional transformation. In particular, we explicate these novel compactons for the trigonometric case, and compare their properties with those of the compactons and solitons in the case of modified KdV equation. Keeping in mind the significance of nonlinear Schr??dinger equation with external source, for pulse propagation through asymmetric twin-core fibres, we hope that the newly found compacton may be launched in a long-haul telecommunication network utilizing asymmetric twin-core fibres.
