时间模上四-点边值问题三个正解的存在性

Existence of Three Positive Solutions to a Four-point Boundary Value Problems on Time Scales

时间模上的二阶非线性动力学方程四一点边值问题至少有一个和两个正解的存在性已经给出,本文给出至少有三个正解的存在性。

Some results are obtained for the existence of at least one,two positive solutions of the above problem by using fixed point theorem.In this paper,we study the existence of at least three positive solutions of a nonlinear second-order four-point boundary value problem for dynamic equations on time scales.
