摘要
基于变分法，运用三临界点定理，得到了一类有小强迫项的二阶离散哈密尔顿系统的周期解的多重性，推广了现有文献的相关结果，并给出例子加以说明．
In the paper, based on variational method, multiple periodic solutions are obtained for a class of second-order discrete Hamiltonian systems with a small forcing term by three critical theorem in Morse theory. Our results extend some existing ones and two examples are showed to illustrate our results.
