时标上动力方程边值问题解的存在性

The Existence of Solutions for Boundary Value Problems of Dynamic Equations on Time Scales

本文在现有时标理论的基础上,借助于锥中twin不动点定理,对一类二阶动力方程边值问题解的存在性进行了研究,得到了至少存在两个正解的判别准则。

Based on the existing standard theory based on,with cone twin fixed point theorem,studied the existence of solutions for value problems of a class of second order nonlinear dynamic equations,get the existence of at least two positive solutions of criterion.
