In this paper we study h-stability of the solutions of nonlinear di？？erence system via the notion of n1-summable similar-ity between its variational systems. Also, we show that two concepts of h-stability and h-stability in variation for nonlinear di？？erence systems are equivalent. Furthermore, we characterize h-stability for nonlinear di？？erence systems by using Lyapunov functions.
