Examines the chain consisting of identical masses , connected by springs stiffness . The chain is on an elastic foundation stiffness . Then the equation of the dynamics of the chain of particles is of the form:
where— moving the -th particle; — difference operator of second order:
— an index that takes arbitrary integer.
