Asymptotically periodic solutions of Volterra system of difference equations

A Volterra system of difference equations of the form x"s(n+1)=a"s(n)+b"s(n)x"s(n)[email protected][email protected]?i=0nK"s"p(n,i)x"p(i) where [email protected]?N, a"s,b"s,x"s:N->R and K"s"p:NxN->R, s=1,2,...,r is studied. Sufficient conditions for the existence of asymptotically periodic solutions of this system are derived.
