Abstract: By using Liapunov function, the author establishes sufficient and necessary conditions for the uniform stability, uniformly asymptotic stability and exponential stability of solutions for a high dimension difference equation. Moreover, the author also proves that the uniformly asymptotic stability implies the boundedness of solutions. A sufficient condition is given for the
existence and uniformly asymptotic stability of almost periodic solutions for almost periodic difference equations.

Key words: Difference equation, Stability, Boundedness, Almost periodicity, Liapunov function
