La ecuación Seno-Gordon perturbada en la dinámica no lineal del ADN

A.H. Salas, J.E. Castillo.

Abstract


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.
