利用下降流的不变集和变分方法，证明了一类二阶离散Neumann边值问题多解的存在性。这些解包括变号解、正解和负解。最后给出一个例子来说明我们的结果。
By using the invariant set of descending flow and variational method, we establish the existence of multiple solutions to a class of second-order discrete Neumann boundary value problems. The solutions include sign-changing solutions, positive solutions, and negative solutions. An example is given to illustrate our results.
