Solitary waves, periodic peakons and compactons on foliations in a Hertz chain model

نویسندگان

چکیده

For a Hertz chain model, by using the methodology of dynamical systems and singular traveling wave theory developed Li Chen [9] to its system defined on two-dimensional foliations in three-dimensional space, under different parameter conditions, existence all possible bounded solutions (solitary solutions, periodic peakons, compactons) is proved. nonlinearity exponent $ k = \frac32, 2 3 as many 23 exact explicit parametric representations above-mentioned are obtained.

Convergence of Solitary-wave Solutions in a Perturbed Bi-hamiltonian Dynamical System. I. Compactons and Peakons

We investigate how the non-analytic solitary wave solutions — peakons and compactons — of an integrable biHamiltonian system arising in fluid mechanics, can be recovered as limits of classical solitary wave solutions forming analytic homoclinic orbits for the reduced dynamical system. This phenomenon is examined to understand the important effect of linear dispersion terms on the analyticity of...

Periodic Travelling Waves and Compactons in Granular Chains

We study the propagation of an unusual type of periodic travelling waves in chains of identical beads interacting via Hertz’s contact forces. Each bead periodically undergoes a compression phase followed by a free flight, due to special properties of Hertzian interactions (fully nonlinear under compression and vanishing in the absence of contact). We prove the existence of such waves close to b...

Solitary Waves and Compactons in a class of Generalized Korteweg-DeVries Equations

We study the class of generalized Korteweg-DeVries equations derivable from the Lagrangian: L(l, p) = ∫ ( 1 2φxφt − (φx) l(l−1) + α(φx) (φxx) 2 ) dx, where the usual fields u(x, t) of the generalized KdV equation are defined by u(x, t) = φx(x, t). This class contains compactons, which are solitary waves with compact support, and when l = p + 2, these solutions have the feature that their width ...

Dissipative Solitary Waves in Periodic Granular Crystals

We provide a quantitative characterization of dissipative effects in one-dimensional granular crystals. We use the propagation of highly nonlinear solitary waves as a diagnostic tool and develop optimization schemes that allow one to compute the relevant exponents and prefactors of the dis-sipative terms in the equations of motion. We thereby propose a quantitatively-accurate extension of the H...

Polychromatic Solitary Waves in a Periodic and Nonlinear Maxwell System

We consider the one-dimensional Maxwell equations with low contrast periodic linear refractive index and weak Kerr nonlinearity. In this context, wave packet initial conditions with a single carrier frequency excite infinitely many resonances. On large but finite time-scales, the coupled evolution of backward and forward waves is governed by nonlocal equations of resonant nonlinear geometrical ...
