?0 ? 0 -boundedness and practical ?0 ? 0 -stability of difference equations ?
In this paper, we develop the notions of ?0 ? 0 -boundedness and practical ?0 ? 0 -stability for difference equations via perturbing cone-valued Lyapunov functions, and obtain sufficient conditions of ?0 ? 0 -boundedness and practical ?0 ? 0 -stability.
