Nonlinear systems with periodic variations of nonlinearity and/or dispersion occur in a
variety of physical problems and engineering applications. The mathematical concept of …

The present review summarizes experimental and theoretical work dealing with self-
organized solitary localized structures (LSs) that are observed in spatially extended …

We present a projection-operator method to express the generalized nonlinear Schrödinger
equation for pulse propagation in optical fibers, in terms of the pulse parameters, called …

We apply variational method to the perturbed nonlinear Schrödinger equation having
quadratic-cubic form of nonlinearity, to study localized optical pulses. Super-Gaussian and …

This investigation presents the generalized cubic-quintic Guizburg-Landau (GCQGL)
equation with higher-order dispersion effects in a nonlinear electrical transmission network …

Propagation characteristics and stability properties of two-component composite screening
photovoltaic spatial solitons have been analyzed in this paper. Employing paraxial ray …

We study the impact of nonlocality and local quintic nonlinearity on the dynamic
characteristic parameters of spatial optical bright soliton and on their interaction and …

We consider the averaged dispersion-managed (DM) fiber system equation, which governs
the dynamics of the core of the DM solitons. For a special case of such a system equation …

We investigate the behavior of the electromagnetic wave that propagates in a metamaterial
for negative index regime. Second-order dispersion and cubic-quintic nonlinearities are …
