基于Banach空间的定点指数理论，找到了时滞差分方程组的正周期解。利用这些结果，还考虑了具有正项和负项的时滞差分方程非平凡周期解的存在性。
Based on the fixed-point index theory for a Banach space, positive periodic solutions are found for a system of delay difference equations. By using such results, the existence of nontrivial periodic solutions for delay difference equations with positive and negative terms is also considered.
