Abstract. The paper develops an algebrotopological approach to the problem of effective selection of real finite-zone solutions of the sine-Gordon equation, which uses the socalledγ-representation on the Riemann surface, in which “action” variables can be computed explicitly.

2 Jun 2016 The classical Sine-Gordon Model is a 2d-field theory and can be characterized as a In the action we have the quantity L/ standing, so. L = 1. They also showed that a pseudo- spectral method with a high order integrator produced smaller deviations in the actions than a finite difference technique. On the  6 Dec 2017 In the context of string theory this action is also a world sheet description of a particular tachyonic background. This has been exploited in. operator of the model in terms of the Sine-Gordon field of the Coulomb gas and hence obtain a dual monopoles [5] which have zero size and infinite action. 18 Sep 2014 We introduce the dynamical sine-Gordon equation in two space dimensions with parameter by the action of Π onto the symbols Ξk a and Ξk.

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, and rediscovered by Frenkel and Kontorova (1939) in their study of crystal dislocations known as the Frenkel–Kontorova 2006-12-01 · The construction of the action variable for the sine–Gordon model The sine–Gordon model has infinitely many local conserved charges, which are in involution with each other. Therefore each solution ϕ ( τ , σ ) defines an infinite-dimensional “invariant torus” which is defined as the orbit of ϕ ( τ , σ ) under the Hamiltonian flows generated by the local conserved charges. The designation “sine-Gordon” is also used for various equations that generalize [1] or bear resemblance to it.

We propose an action for a sine-Gordon-like theory, which reproduces the classical equations of motion of the Green-Schwarz-Metsaev-Tseytlin superstring on AdS 5 × S 5. The action is relativistically invariant. It is a mass-deformed gauged WZW model for SO(4, 1) × SO(5)/SO(4) × SO(4) interacting with fermions.
