Abstract

The aim of this paper is to provide an explicit formula for solutions of the following system of delay difference equations

Fn+1 = AnFn + BnFγn + ƒn, n ∈ ℕ,

where γn = n, αn = [n/k] (the symbol [x] stands for entire part of the real number x and k is a fixed positive integer). (An), (Bn), n ∈ ℕ, are sequences of square matrices of order m, (ƒn) is a sequence of vectors from . From this formula conditions for the stability and asymptotic stability of solutions are derived.

Key words and phrases.: Difference equations; asymptotic theory
