Analytical study of reaction diffusion Lengyel-Epstein system by generalized Riccati equation mapping method

open access: yesScientific Reports, 2023
In this study, the Lengyel-Epstein system is under investigation analytically. This is the reaction–diffusion system leading to the concentration of the inhibitor chlorite and the activator iodide, respectively.

Solitary smooth hump solutions of the Camassa-Holm equation by means of the homotopy analysis method [PDF]

open access: yes, 2008
The homotopy analysis method is used to find a family of solitary smooth hump solutions of the Camassa-Holm equation. This approximate solution, which is obtained as a series of exponentials, agrees well with the known exact solution.

Solitary wave solutions of hierarchy with non-local nonlinearity

open access: yesApplied Mathematics Letters, 2020
The hierarchy of nonlinear differential equations with non-local nonlinearity is considered. Solitary wave solutions of the hierarchy are found. The case of solitary waves for twelfth-order nonlinear differential equation is analyzed in detail.

Metastability of solitary waves in diatomic FPUT lattices

open access: yesMathematics in Engineering, 2019
It is known that long waves in spatially periodic polymer Fermi-Pasta-Ulam-Tsingou lattices are well-approximated for long, but not infinite, times by suitably scaled solutions of Korteweg-de Vries equations.

On spectral stability of solitary waves of nonlinear Dirac equation on a line [PDF]

open access: yes, 2012
We study the spectral stability of solitary wave solutions to the nonlinear Dirac equation in one dimension. We focus on the Dirac equation with cubic nonlinearity, known as the Soler model in (1+1) dimensions and also as the massive Gross-Neveu model ...

Lie symmetry analysis, conservation laws and solitary wave solutions to a fourth-order nonlinear generalized Boussinesq water wave equation

open access: yesApplied Mathematics Letters, 2020
A fourth-order nonlinear generalized Boussinesq water wave equation is studied in this work, which describes the propagation of long waves in shallow water. We employ Lie symmetry method to study its vector fields and optimal systems. Moreover, we derive

Elastic and nonelastic interactional solutions for the (2 + 1)-dimensional Ito equation

open access: yesArab Journal of Basic and Applied Sciences, 2019
In this paper, based on the bilinear form and two new test functions, for the (2 + 1)-dimensional Ito equation, we obtain non-elastic interactional solutions composed of three different types of waves including the solitary wave, the periodic wave and ...

A dimension-breaking phenomenon for water waves with weak surface tension

open access: yes, 2016
It is well known that the water-wave problem with weak surface tension has small-amplitude line solitary-wave solutions which to leading order are described by the nonlinear Schr\"odinger equation. The present paper contains an existence theory for three-

Solitary waves due to x(2):x(2) cascading [PDF]

open access: yes, 1994
Solitary waves in materials with a cascaded x(2):x(2) nonlinearity are investigated, and the implications of the robustness hypothesis for these solitary waves are discussed. Both temporal and spatial solitary waves are studied.
