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 ...

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 ...

Modulational instability of Rossby and drift waves and generation of zonal jets [PDF]

open access: yes, 2010
We study the modulational instability of geophysical Rossby and plasma drill waves within the Charney-Hasegawa-Mima (CH M) model both theoretically, using truncated (four-mode and three-mode) models, and numerically, using direct simulations of CHM ...

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

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 ...

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.

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-
