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. 1979; Bishop and Schneider 1981; Davydov 1985; Infeld and Rowlands 2000, pp. 202 and 240), including the propagation of fluxons in Josephson junctions (a junction between two superconductors), the motion of rigid pendula attached to a In both cases (1) and (2), the sine-Gordon equation admits a Lax representation ∂ L ∂ t = [ L, M], where L and M are linear operators and [ L, M] = L M − M L. This enables one to obtain solutions of the Cauchy problem by using the inverse scattering method. The sine-Gordon equation may be derived from the Lagrangian: (1.2) L = Z dx 1 2 ˚2 t − 1 2 ˚2 x +cos˚−1 ; 2000 Mathematics Subject Classi cation. Primary: 35J20, 58E05; Secondary: 35Q20, 65N30.

20-726, 01000 Mexico, D.F., Mexico´ In this paper, we study the dynamic equation of molecular motion in nematic liquid crystals when there exists the twisting disturbance of the molecular arrangement under the external electric field. After a series of derivation, we find that the evolution equation satisfies the form of Sine-Gordon equation which indicates that the molecular twisting deformation may propagate in the form of equations such as the sine-Gordon equation [1], the nonlinear Schrödinger equation [3–5] and the modi-fied Korteweg–de Vries (KdV) equation [6].

R by iR, we could get the even more popular sine-Gordon equation That is why we call the systems (1.1) 'generalized sine-Gordon equations'. In this paper we are concerned only with purely algebraic properties of the equations, so the substitution R-> iR is harmless. Now, it is well known that the sinh-Gordon equation, or more generally
