SALAS, A.H.  e  CASTILLO, J.E.. La ecuación Seno-Gordon perturbada en la dinámica no lineal del ADN. Rev. mex. fis. [online]. 2012, vol.58, n.6, pp.481-487. ISSN 0035-001X.

We make use of a linear chain of coupled oscillators to construct the Lagrangian in order to give a first approximation for a nonlinear dynamic model of the DNA molecule through the perturbed sine-Gordon equation. By using semi analytic methods, we give exact solutions to perturbed sine-Gordon equation in a travelling wave form. These solutions have some relevant implications in the study of DNA open states. Some of these solutions are new in the open literature.
