| 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. |
| Keywords: | inverse problem of the calculus of variations differential-difference equations potential operators Helmholtz conditions |
