摘要：

A second-order partial difference equation is considered in this paper. By applying critical point theory, we not only establish a series of sufficient conditions on the existence of periodic solutions when the nonlinearity respectively is superlinear, sublinear and asymptotically linear, but also give sufficient conditions on the nonexistence of nontrivial periodic solutions. Finally, we present some examples to illustrate our main results.
