Abstract

We consider the following system of difference equations, ui(k)=∑l∈Igi(k,l)f(l,u1(l),u2(l),...,un(l)),k∈I,1≤i≤n, where I is a subset of ℤ. Our aim is to establish criteria such that the above system has a constantsign periodic and almost periodic solution (u ₁, u₂, ..., u_n). The above problem is also extended to that on ℤ, ui(k)=∑l∈ℤgi(k,l)fi(l,u1(l),u2(l),...,un(l)),k∈ℤ, 1≤i≤n.
