Then for the almost periodic difference systems of general form we establish the criteria of existence for almost periodic solutions.Especially, several existence theorems are proved in terms of discrete Liapunov functions. 关 键 词：ALMOST PERIODIC SEQUENCES UNIFORMLY ALMOST PERIODIC SEQUENCES difference systems ALMOST PERIODIC solutions discrete LIAPUNOV functions
