一类时间测度链上边值问题对称正解的存在性

The Existence of Symmetric Positive Solutions for a Class Boundary Value Problems on Time Measure Chain

运用单调迭代法和不动点定理研究了时间测度链上一类二阶非线性微分方程边值问题对称正解存在的充要条件,并导出了与之相应的线性边值问题解的一些性质.

The necessary and sufficient condition of symmetric positive solutions for a class of second order nonlinear differential equation boundary value problems on time measure chain is studied by using monotone iterative method and fixed point theorem.Some properties of the solutions of the corresponding linear boundary value problems are derived.
