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

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. 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. The equation the sine-Gordon equations can be obtained via the Darboux or B˜acklund transformations [21,37] from already known exact solutions. 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.

Sine-Gordon equation in Encyclopaedia of Mathematics Sine-Gordon equation in EqWorld, the world of mathematical equations Equations (1) and (2) are actually the solutions to these PDEs. (BTW, in Eq.(2), it should be trigonometric arctangent, not the hyperbolic one). One can obtain a $\phi^4$ model as an approximation of the sine-Gordon model, expanding the sine term in the equation or cosine term in the Hamiltonian. The Klein–Gordon equation (Klein–Fock–Gordon equation or sometimes Klein–Gordon–Fock equation) is a relativistic wave equation, related to the Schrödinger equation.It is second-order in space and time and manifestly Lorentz-covariant.It is a quantized version of the relativistic energy–momentum relation.Its solutions include a quantum scalar or pseudoscalar field, a field whose 2021-04-07 Derivation of a generalized double-sine-Gordon equation describing ultrashort-soliton propagation in optical media composed of multilevel atoms Submitted by Emmanuel Lemoine on Wed, 10/29/2014 - 11:46 Titre Derivation of a generalized double-sine-Gordon equation describing ultrashort-soliton propagation in optical media composed of multilevel atoms 3 The Modified sine-Gordon Equation 16 3.1 The modified sine-Gordon equation and its discretization 17 3.1.1 Derivation of the stencil . 17 3.2 Comparing numerical and analytic results for the SGE 21 3.3 Numerical investigations of the MSGE . 24 3.4 The rate of convergence of a … The Solution to the 3D sine-Gordon equation Since sine-Gordon equation is the integrability condition for (6.7).
