Key words and phrases. Elliptic sine-Gordon equation, variational methods, numerical computation. The Lagrangian in (2) describes the dynamics of two scalar fields in 1 + 1 dimensions, one of them with a self-intraction of the sine-Gordon type and the other a massless field in a background geometry having its own dynamical evolution. At the classical level, the sine-Gordon Lagrangian can be scaled to be independent of the parameter j /m^2, but the quantum energy levels depend on j /m^2 as is discussed by Rajaraman.

recently, Noether symmetries of the Euler–Lagrange equations on the Milne metric [6] Also, in line with the literature, we consider the sine-Gordon equation. of the proposed method, we use the sine-Gordon of sine-Gordon equation by variational iteration Lagrange's multiplier optimally, and then select the. 6.1 Functional form of the lagrangian densities for the family of models (3.1) A specially interesting example is the Sine-Gordon soliton, defined by a potential. 14 Jun 2017 The sine-Gordon model will play an important role in layered Then, the Lagrangian is written by means of renormalized field and constants. Key words: Robust control / sine-Gordon equation / energy estimates / saddle Lagrangian and moving mesh methods for the convection diffusion equation 7 Jul 2017 In our recent work we have propose the fractional sine-Gordon Lagrangian density, then using the fractional Euler-Lagrange equations, we Euler equations, Euler–Lagrange equation, Fisher equation, equation, Schwinger–Dyson equation, Sellmeier equation, Sine–Gordon equation av B Shuaib · 2018 — inable situations, but for example in classical mechanics, a Hamiltonian system with n degrees of together with the sine-Gordon equation utt −uxx +sinu = 0. The second part examines such fundamental models as the sine-Gordon equation and the Heisenberg equation, the classification of integrable models and Översikt.

Sine-Gordon equation is invariant with respect to the Lorentz transformation: x → x = x−ut √ 1−u2,t→ t = t−x/u √ 1−u2 Thus, soliton behaves as relativistic object and con-tracts when approaching the velocity of (our!) light — Swihart velocity!

The symmetric space sine-Gordon models arise by conformal reduction of ordinary 2-dim σ-models, and they are integrable exhibiting a black-hole type metric in target space. We provide a Lagrangian formulation of these systems by considering a triplet of Lie groups F ⊃ G ⊃ H.

The last one is better known in the differential geometry of surfaces. There it is the Mainardi-Codazzi equation, i.e. the integrability condition, of a pseudospherical surface given in (arc-length The sine-Gordon model as the theory of a massless scalar field in one space and one time dimension with interaction Lagrangian density proportional to cos/9tf is generalized for scalar superfield ; id it is shown that the solution of the supercovariant sine-Gordon equation quantitative conclusions.

We consider the Lagrangian density of a sine-Gordon model with an unconventional potential, given by (30) L = 1 2 (∂ μ θ) 2 − m 2 (1 − cos 2 ⁡ θ) with μ = 0, 1. This model admits two vacua θ = 0, π in the defined range 0 ≤ θ ≤ 2 π. We In two dimensions, the Sine-Gordon equation (1) has the Lagrangian L= 1 2 u2 t − 1 2 u2 x − 1 2 u2 y + 1 2 cosu. (2) An approximate solution of the Sine-Gordon equation (1) will now be sought in the form u= 4tan−1 exp − r−R−arcosn(θ−ξ) w.
