The equation
The sine-Gordon equation has conserved quantity E1=12π∫−∞+∞φxdx which equals integer number. This conservation law is called topological chargeof solution φ(x,t). The sine-Gordon equation (SGE) is a nonlinear hyperbolic partial differential equation of the form ψtt − ψxx + sin ψ = 0 (4.1) where ψ = ψ(x, t). SGE first arose in the study of surfaces of constant negative curvature
Sine-Gordon Equation A partial differential equation which appears in differential geometry and relativistic field theory. Its name is a wordplay on its similar form to the Klein-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.

This chapter computes a numerical solution by the method of lines (MOL), including detailed discussion of the Matlab routines and the numerical and graphical output. The sine-Gordon equation also appears in a number of other physical applications (Barone 1971; Gibbon et al.

(Muench.), Vol. 40, pp 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 Derivation of a generalized double-sine-Gordon equation describing ultrashort-soliton propagation in optical media composed of multilevel atoms Notes on The Sine Gordon Equation David Gablinger January 31, 2007 Abstract In this seminar, we will introduce the Sine-Gordon equation, and solve it using a Baecklund transfomation. Furthermore, we also give a numeric solution using a split-step algorithm, and also present two physical applications of the Sine-Gordon equation. 1 Abstract In this paper, a novel (3+1)-dimensional sin-Gorden and sinh-Gorden eqaution are derived.
