Chapter 5. 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. On the other hand, Sine-Gordon equations appeared in many physical problems like applications in relativistic field theory, Josephson junc- tions or mechanical transmission lines 4]   .Cited by: 1.

For some limiting cases I can get analytical solutions of that system, for instance, for $\kappa_2$ = 0 the system transforms to one algebraic equation and one so-called double sine-Gordon equation for the function $\theta$, which solution in turn can be expressed via Jacobi elliptic functions. I am currently trying to show a the sine-Gordon equation is satisfied by a 'soliton-antisoliton' solution. Basically, I need to differentiate twice w.r.t. t and x separately and plug in everything as usual but my expression is getting extremely complicated and I don't know how to deal with the sin. On the other hand, Sine-Gordon equations appeared in many physical problems like applications in relativistic field theory, Josephson junc- tions or mechanical transmission lines 4]   .Cited by: 1. Sine-Gordon equation. The sine-Gordon equation is a nonlinear hyperbolic partial differential equation in 1 + 1 dimensions involving the d'Alembert operator and the sine of the unknown function. It was originally introduced by Edmond Bour () in the course of . The sin function operates element-wise on arrays. The function accepts both real and complex inputs. The function accepts both real and complex inputs. For real values of X, sin.] Sine gordon equation matlab This is no longer a soliton equation, but it has many similar properties, as it is related to the sine-Gordon equation by the analytic continuation (or Wick rotation) y = it. The elliptic sinh-Gordon equation may be defined in a similar way. A generalization is given by Toda field theory. Quantum version.

The periodic problem for the sine-Gordon equation can be studied by means of an algebraic-geometric method (similar to the case of the Korteweg–de Vries equation). In particular, one obtains explicit expressions for the finite-gap solutions of the sine-Gordon equation in terms of -functions on the corresponding Abelian varieties. The sine-Gordon equation is a nonlinear partial di erential equation. It is known that the sine-Gordon has soliton so-lutions in the 1D and 2D cases, but such solutions are not known to exist in the 3D case. Several numerical solutions to the 1D, 2D, and 3D sine-Gordon equation are presented and comments are given on the nature of the solutions. 1.

In this section, we give the basic theory of the sine–Gordon equation (and the variety of its traveling–wave solutions), as spatiotemporal models of nonlinear excitations in complex physical systems. Sine–Gordon equation (SGE) SGE is a real-valued, hyperbolic, nonlinear wave equation deﬁned on R1,1, which appears. $\begingroup$ I have got the equation (1) from Mark srednicki, the author got this equation by explaining spontaneous symmetry breaking and then turned into equation (1). Now I'm confused with the sine-Gordon theory which is also 2 dimensional like equation (1). sine-Gordon equation David Jäderberg, Andreas Gådin This project deals with creating a numerical solver of the sine-Gordon equation using the summation- by- parts and simultaneous approximation term method in combination with a finite difference time- stepping method as well as a Runge-Kutta time-stepping method. For other exact solutions of the sine-Gordon equation, see the nonlinear Klein–Gordon equation with f(w) =bsin(‚w). 5–. The sine-Gordon equation is integrated by the inverse scattering method.

They have the advantage that there is a. In this paper, we develop a numerical method for the N-dimensional sine-Gordon equation using differentiation matrices, in the theoretical frame of matrix differential equations. Our method avoids calculating exponential matrices, is very intuitive and easy to express, and can be implemented without toil in any number of spatial dimensions. the SINE-GORDON Equation in To understand quantitatively how soli-tons can result from a delicate balance of dispersion and nonlinearity, let us be-gin with the linear, dispersionless,bi- directional wave equation By direct substitution into Eq. 1, it is is a solution for any functions f and g. “solitary waves,” one moving to the left. function. If we assign the nonlinear force gu u()=sin in (1) then it is known as Sine- Gordon equation. The Klein-Gordon equation plays an important role in mathematical physics    and attracted more attention from scientists and engineering in different matter like investigation of the interaction of solutions in a collisionless.
