Several definitions of partial set-stability relative to a difference equations are considered,and stability theorems are established. Sufficient conditions for stability are obtained by employing the idea of Liapunov function. Next, we investigate partial set-stability for Large-scale discrete systems. Several Stability theorems are obtained. 展开更多
