摘要
In order to obtain the conditions for the existence of periodic and almost periodic solutions of Volterra difference equations, x(n + 1) = f(n; x ( n))+ Sigma(n)(s=-infinity) F(n, s, x(n + s); x(n)), we consider certain stability properties, which are referred to as (K, rho)-weakly uniformly-asymptotic stability and (K, rho)-uniformly asymptotic stability. Moreover, we discuss the relationship between the rho-separation condition and the uniformly-asymptotic stability property in the rho sense.
