摘要
This paper studies the nonautonomous nonlinear system of difference equationsΔx(n)=A(n)x(n)+f(n,x(n)),n∈Z,(*) where x(n)∈R;,A(n)=(a;(n))N×N is an N×N matrix,with a-(ij)∈C(R,R) for i,j= 1,2,3,...,N,and f=(f;,f;,...,f;);∈C(R×R;,R;),satisfying A(t+ω)=A(t),f(t+ω,z)=f(t,z) for any t∈R,(t,z)∈R×R;andωis a positive integer.Sufficient conditions for the existence ofω-periodic solutions to equations (*) are obtained.
