In this Letter, by using a novel extended homoclinic test approach (EHTA) we obtain two new types of exact periodic solitary-wave and kinky periodic-wave solutions for Jimbo-Miwa equation. Moreover, we investigate the strangely mechanical features of wave solutions. These results enrich the variety of the dynamics of higher-dimensional nonlinear wave field. 相似文献

The extended homoclinic test function method is a kind of classic, efficient and well-developed method to solve nonlinear evolution equations. In this paper, with the help of this approach, we obtain new exact solutions (including kinky periodic solitary-wave solutions, periodic soliton solutions, and crosskink-wave solutions) for the new (2+1)-dimensional KdV equation. These results enrich the variety of the dynamics of higher-dimensional nonlinear wave field. 相似文献

In this paper, we obtain a new class of exact cross kink-wave and periodic solitary-wave solutions for Jimbo-Miwa equation by using two-soliton method, bilinear method and transforming parameters into complex ones. Moreover, we investigate singular and non-singular phenomenons of solutions. In addition, we study the resonance and non-resonance interactions between y-t periodic solitons and different line solitons. 相似文献

Abstract An efficient method for constructing of particular solutions of some nonlinear partial differential equations is introduced. The method can be applied to nonintegrable equations as well as to integrable ones. Examples include multisoliton and periodic solutions of the famous integrable evolution equation (KdV) and the new solutions, describing interaction of solitary waves of nonintegrable equation. 相似文献

The (3+1)-dimensional Jimbo-Miwa (JM)
equation is solved approximately by using the conformal invariant
asymptotic expansion approach presented by Ruan. By solving the new
(3+1)-dimensional integrable models, which are conformal invariant
and possess Painlevé property, the approximate solutions are
obtained for the JM equation, containing not only one-soliton
solutions but also periodic solutions and multi-soliton solutions.
Some approximate solutions happen to be exact and some approximate
solutions can become exact by choosing relations between the parameters properly. 相似文献

In this letter, we study an integrable Camassa-Holm hierarchy whose high-frequency limit is the Camassa-Holm equation. Phase plane analysis is employed to investigate bounded traveling wave solutions. An important feature is that there exists a singular line on the phase plane. By considering the properties of the equilibrium points and the relative position of the singular line, we find that there are in total three types of phase planes. Those paths in phase planes which represented bounded solutions are discussed one-by-one. Besides solitary, peaked and periodic waves, the equations are shown to admit a new type of traveling waves, which concentrate all their energy in one point, and we name them deltons as they can be expressed as some constant multiplied by a delta function. There also exists a type of traveling waves we name periodic deltons, which concentrate their energy in periodic points. The explicit expressions for them and all the other traveling waves are given. 相似文献

The Camassa-Holm equation, Degasperis-Procesi equation and Novikov equation are the three typical integrable evolution equations admitting peaked solitons. In this paper, a generalized Novikov equation with cubic and quadratic nonlinearities is studied, which is regarded as a generalization of these three well-known studied equations. It is shown that this equation admits single peaked traveling wave solutions, periodic peaked traveling wave solutions, and multi-peaked traveling wave solutions. 相似文献

The Estabrook-Wahlquist prolongation of a one-parameter family of evolution equations is carried out explicitly. It is shown that a non-Abelian prolongation algebra is obtained only for that parameter value for which the prolonged equation belongs to a known class of integrable equations. A Bäcklund transformation is constructed for the integrable case, and periodic, kink and bell-type solutions are displayed. 相似文献

In this paper, we study an integrable generalization of the associated Camassa–Holm equation. The generalized system is shown to be integrable in the sense of Lax pair and the bilinear Bäcklund transformations are presented through the Bell polynomial technique. Meanwhile, its infinite conservation laws are constructed, and conserved densities and fluxes are given in explicit recursion formulas. Furthermore, a Darboux transformation for the system is derived with the help of the gauge transformation between two Lax pairs. As an application, soliton and periodic wave solutions are given through the Darboux transformation. 相似文献

In this paper, we first consider
exact solutions for Lienard equation
with nonlinear terms of any order.
Then, explicit exact bell and kink profile solitary-wave solutions
for many nonlinear evolution equations are obtained by means of
results of the Lienard equation and proper deductions, which transform
original partial differential equations into the Lienard one.
These nonlinear equations include compound KdV, compound KdV-Burgers,
generalized Boussinesq, generalized KP and Ginzburg-Landau
equation. Some new solitary-wave solutions are found. 相似文献

Considered herein is the dynamical stability of the single peaked soliton and periodic peaked soliton for an integrable modified Camassa-Holm equation with cubic nonlinearity. The equation is known to admit a single peaked soliton and multi-peakon solutions, and is shown here to possess a periodic peaked soliton. By constructing certain Lyapunov functionals, it is demonstrated that the shapes of these waves are stable under small perturbations in the energy space. 相似文献

In this paper, we discuss conditional stability of solitary-wave solutions in the sense of Liapunov for the generalized compound KdV equation and the generalized compound KdV-Burgers equations. Linear stability of the exact solitary-wave solutions is proved for the above two types of equations when the small disturbance of travelling wave form satisfies some special conditions. 相似文献

A new method of finding the periodic solutions for the equations integrable within the framework of the AKNS scheme is reviewed. The approach is a modification of the known finite-band integration method, based on the re-parametrization of the solution with the use of algebraic resolvent of the polynomial defining the solution in the finite-band integration method. This approach permits one to obtain periodic solutions in an effective form necessary for applications. The periodic solutions are found for such systems as the nonlinear Schrödinger equation, the derivative nonlinear Schrödinger equation, the Heisenberg model, the uniaxial ferromagnet, the AB system, and self-induced transparency and stimulated Raman scattering equations. The modulation Whitham theory describing the slow modulation of periodic waves is expressed in a form convenient for applications. The Whitham equations are obtained for all abovementioned cases. The technique developed is applied to the nonlinear theory of modulational instability describing the transformation of a local disturbance expanding into a nonuniform region presented as a modulated periodic wave whose evolution is governed by the Whitham equations. This theory explains the formation of solitons on the sharp front of a long pulse. 相似文献

Bifurcations and Single Peak Solitary Wave Solutions of an Integrable Nonlinear Wave Equation 下载免费PDF全文

Dynamical system theory is applied to the integrable nonlinear wave equation $u_t±(u^3−u^2)x+(u^3)xxx=0$. We obtain the single peak solitary wave solutions and
compacton solutions of the equation. Regular compacton solution of the equation corresponds to the case of wave speed $c$=0. In the case of $c^6$≠0, we find smooth soliton
solutions. The influence of parameters of the traveling wave solutions is explored by
using the phase portrait analytical technique. Asymptotic analysis and numerical simulations
are provided for these soliton solutions of the nonlinear wave equation. 相似文献

Painleve properties and exact solutions for the high-dimensional Schwartz Boussinesq equation 下载免费PDF全文
The usual (1+1)-dimensional Schwartz Boussinesq equation is extended to the (1+1)-dimensional space-time symmetric form and the general (n+1)-dimensional space-time symmetric form. These extensions are Painleve integrable in the sense that they possess the Painleve property. The single soliton solutions and the periodic travelling wave solutions for arbitrary dimensional space-time symmetric form are obtained by the Painleve-Backlund transformation. 相似文献

For a higher-dimensional integrable nonlinear dynamical system, there are abundant coherent soliton excitations. With the aid of an improved projective Riccati equation approach, the paper obtains several types of exact solutions to the (2+l)-dimenslonal dispersive long-wave equation, including multiple-soliton solutions, periodic soliton solutions, and Weierstrass function solutions. From these solutions, apart from several multisoliton excitations, we derive some novel features of wave structures by introducing some types of lower-dimensional patterns. 相似文献
