Hence we can replace z by z +z0, where z0 is any constant, in the above solutions of equation (1.4). We will apply this method to the sine-Gordon, sinh-Gordon, and double-sine-Gordon equations. In addition to the known solutions of theses equations, some new solutions will also be given. II The sine-Gordon Equation

Interesting quantities such as the kink mass, the charge and the energy density is computed in both phi^4- and the sine-Gordon theory. A breather is a localized periodic solution of either continuous media equations or discrete lattice equations. The exactly solvable sine-Gordon equation and the focusing nonlinear Schrödinger equation are examples of one-dimensional partial differential equations that possess breather solutions. solution of sine-Gordon equation u = 2arccos[sech z p ¡c]; c < 0: (2.9) Using the identity tan2 u 4 = 1¡cos u 2 1+cos u 2; (2.10) we may write the solution (2.9) in the form u = 4arctan[exp(z p ¡c)]¡…: (2.11) The solutions (2.11) was also given in [7]. Case(2) c0 = c2 2 4c4: In this case, we have k = ¡2.

Key Words: soliton solution, sine-Gordon, DNA, graphic. Introduction There are many models of DNA, both the linear ones and the nonlinear ones [1]. One interesting model in this regard is the sine-Gordon model of DNA as proposed by Salerno [2], see also Daniel and Vasumathi [3].

The method proposed aris. The solitons, or kinks, are the most important ones.

In particular, if u is a solution of the sine-Gordon equation, u xy= sinu, then the auto-B acklund transformation is the system v x= u x+ 2asin(u+ v 2) v y= u y+ 2 a sin(v u 2) Yousef, A.M., Rida, S.Z., Ibrahim, H.R.: Approximate solution of fractional-order nonlinear sine-Gordon equation.

It is well known in the commutative case that one may obtain reductions by imposing periodic conditions on the θ n. Similarly in the non-Abelian case, one can make periodic reductions of . From now on, we only … The fractional sine-Gordon equation with the Riemann– Liouville fractional derivative is used as an example to solve its periodic solution by the homotopy perturbation method.

In this scheme we advance the solution of the (2+1) sine-Gordon partial differential Equation (1) from nth plane to (n+1)th plane by replacing u xx by implicit finite difference approximation at the (n+1)th plane. Similarly, u tt, u yy and u t are replaced by an explicit central finite difference approximation at the nth plane as in equations

(Although the reason for the factor of 4 is not entirely clear.) Plugging the ansatz ( 16 ) into the Sine-Gordon equation (1) then gives 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. References Steuerwald, R., Uber enneper’sche Fl¨ achen und B¨ ¨acklund’sche Transformation, Abh. Bayer. Akad. Wiss.
