中文摘要：

利用五个泛函的不动点定理,研究带有p-Laplacian算子的二阶微分方程组分别在3种边界条件下至少3个正解的存在性,并给出例子验证所得结论。

英文摘要：

Using five functions fixed point theorem,we prove the existence of at least three positive solutions to second-order systems with p-Laplacian under three kinds of boundary conditions,respectively.We give an example to illustrate our result.
