Abstract: Abstract The perturbed nonlinear Schrodinger's equation with anti-cubic nonlinearity is studied with the aid of semi-inverse variational principle. The perturbation terms that are included are inter-modal dispersion, third and fourth order dispersion, nonlinear dispersion and… read more here.

DOI: 10.1016/j.ijleo.2019.163322

Abstract: Abstract This paper obtains highly dispersive perturbed bright 1-soliton solution with cubic–quintic–septic nonlinearity by the aid of semi-inverse variational principle. The relation between the parameters, for sustaining solitons, naturally emerge during the course of soliton… read more here.

DOI: 10.12693/aphyspola.141.64

Abstract: In this paper we have chosen to work with two different approaches to solving the inverse problem of the calculus of variation. The first approach is based on an integral representation of the Lagrangian function… read more here.
