STABILITY OF NONLINEAR TIME-VARYING DISCRETE SYSTEMS
非线性时变离散系统的稳定性

In this paper,stability of nonlinear time-varying discrete systems is investigated by meansof Gauss-Seidel interation method.Some algebraic criteria of stability are obtained.The con-struction of Lyapunov function is avoided.A new approach is found for stability analysis ofdiscrete systems.
