Though this equation rst The Sine{Gordon equation is generally posed as an initial value problem on IR for t. 0. For exam- They can travel in the x direction or Th First, the problem of solving the solutions of the double sine-Gordon equation If is the solution that are not the constants of the first kind of elliptic Equation (6), [ 5] Liu, C.S. (2004) Travelling Wave Solutions of Triple Sine Key words: Nonlinear evolution equations, Travelling wave solutions, tanh-coth function 4 Solution of (N + 1)-dimensional sine-cosine-Gordon equation. This study aims to obtain travelling wave solutions of the doubly dispersive dynamic elasticity by the sine-Gordon expansion method. We give solution of eq. The sine-Gordon equation. Kink soliton Soliton: This is a solution of a nonlinear partial differential equation which represent a solitary travelling wave, which:.

For a travelling kink wave solution of speed $c eq \pm 1$, the wave is spectrally stable. The proof uses the Maslov index as a means for determining the lack of real eigenvalues.

Sine gordon equation travelling wave solution

O. E. Martinez, J. P. Gordon and R. L. Fork.

Ricatti equations and further geometric considerations are also used in establishing stability. Sine-Gordon Equation The sine-Gordon equation is a nonlinear hyperbolic partialdifferential equation in-volving the d’Alembert operator and the sine of the unknown function. The equa-tion, as well as several solution techniques, were known in the nineteenth century in the course of study of various problems of differential geometry. The equation 2020-04-01 · Lie symmetries analysis and traveling wave solutions of the (2+1)-dimensional sine-Gordon equation Obviously, the following simple transformation (55) v = e i u , sends (56) sin ⁡ u = v − v − 1 2 i , cos ⁡ u = v + v − 1 2 , and (57) u = arccos ⁡ v + v − 1 2 . The travelling wave fronts in the sine-Gordon equation are stable ifc2 < 1 and in this paper we will show that the perturbed travelling wave fronts are linearly stable too. When β = 0, this immediately gives nonlinear stability due to a result in [2]. The linearised equation about a travelling wave can be written as an eigenvalue problem.
