摘要：

We obtain a travelling-wave solution of a generalised nonlinear Schrodinger equation with an additional term of the form Gamma(psi(x, t)) = ) lambda psi(x, t)(q), where lambda and q are real constants. Moreover, we show that the density of energy of the system for the travelling-wave solution presents a Lorentzian solitary wave behaviour. (C) 2019 Elsevier B.V. All rights reserved.
