Bifurcation Phenomena of Nonlinear Waves in a Generalized Zakharov-Kuznetsov Equation

open access: yesAdvances in Mathematical Physics, 2013
We study the bifurcation phenomena of nonlinear waves described by a generalized Zakharov-Kuznetsov equation ut+au2+bu4ux+γuxxx+δuxyy=0. We reveal four kinds of interesting bifurcation phenomena.

Numerical simulation of capillary gravity waves excited by an obstacle in shallow water; pp. 278–284 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2015
Capillary gravity waves excited by an obstacle are investigated by numerical simulations. Under the resonant condition for which large-amplitude solitary waves are generated, solutions of the Euler equations show that the capillary effects induce the ...

Numerical Study on Collisions of Solitons of Surface Waves in Finite Water Depth

open access: yesFluids, 2023
Head-on collisions between two solitary waves in the framework of the nonlinear Schrödinger (NLS) equation were investigated using the Fourier spectral method. When solitary waves undergo collision, the peak value of surface elevation (hereafter referred

Hybrid Solitary Waves and Shock Waves for Double-Layered Fluid Flow with Dispersion Triplet: Zaremaoghaddam and Gear-Grimshaw Models (mKdV Equation)

open access: yesEast European Journal of Physics
The current paper recovers hybrid solitary waves for double–layered shallow water waves with the basic platform being the mKdV equation. The selected models are the Zaremaoghaddam equation and the Gear–Grimshaw equation. The integration algorithm adopted

Dissipative Nonlinear Schrödinger Equation for Envelope Solitary Rossby Waves with Dissipation Effect in Stratified Fluids and Its Solution

open access: yesAbstract and Applied Analysis, 2014
We solve the so-called dissipative nonlinear Schrödinger equation by means of multiple scales analysis and perturbation method to describe envelope solitary Rossby waves with dissipation effect in stratified fluids.

The solitary wave of asexual evolution [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
Using a previously undescribed approach, we develop an analytic model that predicts whether an asexual population accumulates advantageous or deleterious mutations over time and the rate at which either process occurs. The model considers a large number of linked identical loci, or nucleotide sites; assumes that the selection coefficient per site is ...

A global investigation of solitary-wave solutions to a two-parameter model for water waves [PDF]

open access: yes, 1996
The model equation (2r''''/15)-(br'')+(ar)+(3r^2/2)-((r')^2/2)+[rr']'=0 arises as the equation for solitary-wave solutions to a fifth-order long-wave equation for gravitycapillary water waves.

On the generation of solitary waves observed by Cluster in the near-Earth magnetosheath [PDF]

open access: yesNonlinear Processes in Geophysics, 2005
Through case studies involving Cluster waveform observations, solitary waves in the form of bipolar and tripolar pulses have recently been found to be quite abundant in the near-Earth dayside magnetosheath.

Forced ILW-Burgers Equation as a Model for Rossby Solitary Waves Generated by Topography in Finite Depth Fluids

open access: yesJournal of Applied Mathematics, 2012
The paper presents an investigation of the generation, evolution of Rossby solitary waves generated by topography in finite depth fluids. The forced ILW- (Intermediate Long Waves-) Burgers equation as a model governing the amplitude of solitary waves is ...
