Unperturbed sine-Gordon equation has exact solution: φ(x,t) = 4arctanexp ±√x−ut 1−u2 This is a solitary wave or soliton. It can move with velocity 0 ≤ u<1 (i.e. c¯0!). Picture. Soliton is a kink which changes the Josephson phase from 0 to 2π (soliton) or from 2π to 0 (anti-soliton). The field of soliton is h = φ x = 2 cosh(√x−ut 1−u2),h| x=0 =2 For other exact solutions of the sine-Gordon equation, see the nonlinear Klein–Gordon equation with f(w) =bsin(‚w). 5–.

Similarly, u tt, u yy and u t are replaced by an explicit central finite difference approximation at the nth plane as in equations Slower-than-light multi-front solutions of the Sine-Gordon in (1+2) dimensions, constructed through the Hirota algorithm, are mapped onto spatially localized structures, which emulate free, spatially extended, massive relativistic particles. A localized structure is an image of the junctions at … The sine-Gordon Equation on a Finite Interval 519 We are interested in the large time asymptotic behavior of the solution of such prob-lems, and in understanding the generation of … The sine-Gordon equation has the following 1-soliton solutions: φ soliton ( x , t ) := 4 arctan ( e m γ ( x − v t ) + δ ) {\displaystyle \varphi _{\text{soliton}}(x,t):=4\arctan \left(e^{m\gamma (x-vt)+\delta }\right)\,} means that interchanging space and time variables preserves the solution, as required by the symmetry of the sine-Gordon equation (1). (Although the reason for the factor of 4 is not entirely clear.) Plugging the ansatz into the Sine-Gordon equation (1) then gives mulas for exact solutions to the sine-Gordon equation.
solutions to the sine Gordon equation. Representing the kernels of the Marchenko equation in a separated form by using a suitable triplet of constant real matrices (A;B;C), we explicitly solve the Marchenko equations by separation of variables. The solution of the sine-Gordon
Factor B = B+ B−, solve (minimum degree solution). AF + B−G = C. If there is any problem you have many solutions for this.
The sine-Gordon model is discussed and analyzed within the framework of the renormalization group theory. A perturbative renormalization group procedure is described, in which the sine-Gordon field is decomposed into slow and fast modes. An effective theory for the slow modes is derived and rescaled to yield the flow equations for the model. The resulting Kosterlitz–Thouless phase diagram is

We have found these solutions of the equation in the trigonometric, complex and hyperbolic function forms. solutions of sine-Gordon equation are obtained by means of a constructed Wronskian form expansion method. The method is based upon the forms and structures of Wronskian solutions of sine-Gordon equation, and the functions used in the Wronskian determinants do …
The nonlinear Sine-Gordon equation is one of the widely used partial differential equations that appears in various sciences and engineering. The main purpose of writing this article is providing an efficient numerical method for solving two-dimensional (2D) time-fractional stochastic Sine–Gordon equation on non-rectangular domains.
