Variational Method for Studying Solitons in the KdV equation

High Energy Physics - Phenomenology 2009-10-22 v1

Abstract

We use a class of trial wave functions which are generalizations of gaussians to study single soliton approximate analytic solutions to the KdV equations. The variational parameters obey a Hamiltonian dynamics obtained from the Principle of Least Action. We get extremely accurate approximate single soliton solutions including their time dependence using this method.
