摘要
主要讨论了二阶非自治(q,p)-Laplace方程组解的存在性。借助一个新的条件,可以说明二阶非自治(q,p)-Laplace方程组相应的泛函满足PS条件,得到二阶非自治(q,p)-Laplace方程组解的一些存在性定理,最后借助鞍点定理给予证明。
The existence of solution of second-order nonautonomous equations with (q, p) - Laplacian is discussed. Under the new condition, it is well known that second-order nonautonomous equations with (q, p) -Laplacian corresponds to functional satisfies PS condition. Some existence theorems of unique solution of second-order nonautonomous equations with (q, p) -Laplacian are obtained by using the sad- dle point theorem.
