The method proposed arises from a two-step, one parameter method for the numerical solution of second-order ordinary differential equations. Though implicit in nature, the method is applied explicitly. Global extrapolation in both space and time is used to improve Derivation of a generalized double-sine-Gordon equation describing ultrashort-soliton propagation in optical media composed of multilevel atoms Herve Leblond,´ 1 Houria Triki, 2 and Dumitru Recent work has shown that the Sine-Gordon and SIT equations describe the evolution of the envelope of baroclinic wave packets in a two-layer rapidly rotating fluid. The significance of this result is discussed with reference to the optical SIT problem and it is shown how this type of rotating fluid behaves in a simple way as a two-level pseudospin system. sine-Gordon Lax system Numerical Scheme for nding the Lax spectrum Algebraic Solitons Rogue Waves Conclusion How to construct a rogue wave The one-fold Darboux Transformation (DT) creates new solutions to the sine-Gordon equation with a solution u to the sine-Gordon equation and solution ( 1;p 1 q 1) to the Lax pair, u^ ˘= u ˘+ 4 1p 1q 1 p2 1 Double sine-Gordon (DsG) equation has been widely applied to describe various phenomena in physics and other scientific fields, such as superfluid, Josephson arrays, ferromagnetic materials, The initial value problem for the sine-Gordon equation is solved by the inverse-scattering method.

The initial value problem for this equation with the constant Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share … 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 (1862) in the course of study of surfaces of constant negative curvature as the Gauss–Codazzi equation for surfaces of curvature –1 in 3-space, [1] and rediscovered by Frenkel Calculations of quantum corrections to soliton masses generally require both the vacuum sector and the soliton sector to be regularized. The finite part of the quantum correction Created Date: 1/31/2007 12:36:45 AM R by JR, we could get the even more popular sine-Gordon equation Rxt = sin R. That is why we call the systems (1.1)'generalized sine-Gordon equations'. In this paper we are concerned only with purely algebraic properties of the equations, so the substitution R ~ iR is harmless. The sine-Gordon (sG) equation is a signiﬁcant example of evolution problem belonging to the class of integrable PDEs in one space dimensions. We consider the hyperbolic form of this equation, which is given by qxt +sinq = 0, q = q(x,t).

The sine-Gordon equation was the fourth nonlinear partial diﬁerential equation whose initial-value problem was discovered [2,3] to be solvable by the inverse scattering transform method. The generalized sine-Gordon (sG) equation where u = u ( x , t ) is a scalar-valued function, ν is a real parameter, ∂ 2 x = ∂ 2 /∂ x 2 and the subscripts t and x appended to u denote partial differentiation, has been derived in [ 1 ] using bi-Hamiltonian methods.
