【Abstract】 From the study on the boundary of solution to discrete differential-algebraic systems,it is concluded that if the solution to discrete differential-algebraic system periodically is ultimately bounded,there must be a periodic solution to the system.When Lyapunov function is employed to study a class of discrete differential-algebraic system, the sufficient condition is found in the periodic solution to the discrete differential-algebraic system provided.更多还原
