A Nonlinear Wave Equation with Jumping Nonlinearity

open access: yesDiscrete and Continuous Dynamical Systems, 1998
The authors study multiplicity of solutions \(u(x,t)\) for a piecewise linear perturbation of the one-dimensional wave operator \(u_{tt}-u_{xx}\) under Dirichlet boundary condition on the interval \((-{\pi\over 2}, {\pi\over 2})\) and periodic condition on \(t\), that is \[ \begin{cases} u_{tt}-u_{xx}+g (u)=f(x,t) \text{ in }\left(-{\pi\over 2}, {\pi ...

Solitary wave solutions for the generalized Zakharov–Kuznetsov–Benjamin–Bona–Mahony nonlinear evolution equation

open access: yesJournal of Ocean Engineering and Science, 2017
In this paper, we utilize the exp(−φ(ξ))-expansion method to find exact and solitary wave solutions of the generalized Zakharov–Kuznetsov–Benjamin–Bona–Mahony nonlinear evolution equation. The generalized Zakharov–Kuznetsov–Benjamin–Bona–Mahony nonlinear

Nonlinear Waves in Rods and Beams of Power-Law Materials

open access: yesJournal of Applied Mathematics, 2017
Some novel traveling waves and special solutions to the 1D nonlinear dynamic equations of rod and beam of power-law materials are found in closed forms. The traveling solutions represent waves of high elevation that propagates without change of forms in ...

The modified Korteweg - de Vries equation in the theory of large - amplitude internal waves [PDF]

open access: yesNonlinear Processes in Geophysics, 1997
The propagation of large- amplitude internal waves in the ocean is studied here for the case when the nonlinear effects are of cubic order, leading to the modified Korteweg - de Vries equation.

Autoresonant excitation of space-time quasicrystals in plasma

open access: yesPhysical Review Research, 2022
We demonstrate theoretically and numerically that a warm fluid model of a plasma supports space-time quasicrystalline structures. These structures are highly nonlinear, two-phase, ion acoustic waves that are excited autoresonantly when the plasma is ...

Chaos in Magnetoplasmas [PDF]

open access: yesNonlinear Processes in Geophysics, 1999
A nonlinear wave, in general, is equivalent to a nonlinear dynamical system, which exhibits the phenomena of chaos. By means of techniques of nonlinear dynamical systems, we have investigated the conditions under which nonlinear Alfvén waves and lower-

A Comparative Study on Generation and Propagation of Nonlinear Waves in Shallow Waters

open access: yesJournal of Marine Science and Engineering, 2023
This study is concerned with the generation and propagation of strongly nonlinear waves in shallow water. A numerical wave flume is developed where nonlinear waves of solitary and cnoidal types are generated by use of the Level I Green-Naghdi (GN ...
