摘要
利用上下解方法,研究一类非线性二阶微分系统解及正解的存在性熏得到了该微分系统解的存在性结论熏同时给出了应用的例子。
Upper and lower solutions method is employed to study the existence of a nonlinear second-order differential system's solution and its positive solution. It is concluded that the solution of the differential system does exist. And an example is given to illustrate the application.
