摘要
研究了一类非线性三阶常微分方程组三点边值问题,通过运用Leggett-Williams不动点定理和Leray-schauder不动点定理建立了该问题至少有三个正解及任意奇数个正解的存在性准则.
By using Leggett-Williams fixed point theorem and Leray-Schauder fixed point theorem,this paper,establishes the existence criteria of three positive solutions as well as arbitary odd positive solutions to the three-point boundary value problems for third-order differential equations.
