The two-dimensional (2D) sine-Gordon model describes the Kosterlitz-Thouless transition of the 2D classical XY model[13, 14]. The 2D sine-Gordon model is mapped to the Coulomb gas model with logarithmic interaction[15].

Worthyc a FENOMEC, Department of Mathematics and Mechanics, IIMAS, Universidad Aut´onoma de M ´exico, Abstract. In the present chapter, we consider two prototypical Klein–Gordon models: the integrable sine-Gordon equation and the non-integrable ϕ 4 model. We focus, in particular, on two of their principal solutions, namely the kink-like heteroclinic connections and the time-periodic, exponentially localized in space breather waveforms.

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

This lattice model is one of the possible regularizations of the quantum field sine the sine-Gordon equation; here for the ﬁrst time, we will point out its periodic solution. An effective mathematical approach to noise and uncertain properties of nonlinear vibrations arising in the engineering of architecture can be modeled by the fractional calculus.
