Bright and dark soliton solutions for the perturbed nonlinear Schrödinger’s equation with Kerr law and non-Kerr law nonlinearity

摘要

In this paper new dark and bright soliton solutions for the perturbed nonlinear Schrödinger’s equation with Kerr law and non-Kerr law nonlinearity are obtained. The studied forms of nonlinearity are Kerr-law, power-law, parabolic-law and dual-power law.
