Abstract Complex Ginzburg–Landau (CGL) equations serve as canonical models in a great
variety of physical settings, such as nonlinear photonics, dynamical phase transitions …

In this projected paper, we study on the Ivancevic option pricing model. We apply two
important methods, namely, rational sine-Gordon expansion method which is recently …

The core of this research is to investigate the system of equations for the ion sound and
Langmuir waves through the Bernoulli sub-equation method. It is one of the most effective …

Parametric amplifiers based on coupled-core fibers and coupled integrated waveguides are
promising devices for delivering broadband and flat gain spectrum with low noise figure in …

We present an analytical and numerical study of optical parametric amplification in coupled
waveguides amplifiers accounting for presence of losses and spatially dependent coupling …

This study uses a semi-inverse variational technique to investigate the unknown dynamical
behaviour of optical solitons in the solutions of a nonautonomous (1+ 1)-dimensional …

We report in this paper the influence of the discrete lattice spacing on the formation of
intrinsic localized structures in the Salerno model. Through the linear stability analysis …

Optical rogue waves and its variants have been studied quite extensively in the context of
optical fiber in recent years. It has been realized that dispersion management in optical fiber …

We have investigated the modulation instability (MI) analysis of a nonautonomous (3+ 1)-
dimensional coupled nonlinear Schrödinger (NLS) equation with time-dependent dispersion …

It is known that after a particular distance of evolution in fiber lasers, two (input) asymmetric
soliton like pulses emerge as two (output) symmetric pulses having same and constant …
