Inverse Problem of the Calculus of Variations for Systems of Differential-Difference Equations of Second Order
A. M. Popov Peoples Friendship University of Russia
Abstract:
The inverse problem of the calculus of variations for second-order nonlinear and linear systems of differential-difference equations is considered. The relationship between the formal potentiality of a linear system with constant coefficients and the parity of its characteristic function is established.
