带变号格林函数的三阶三点差分方程边值问题的多解性

Multiple Positve Solutions of a Discrete Third-order Three-point BVP with Sign-changing Green's Function

摘要:

在本文中，我们考虑离散非线性三阶三点边值问题正解的存在性，这个问题的格林函数是变号的，所用的方法的锥上的不动点.

Abstract:

In this paper, we consider the existence of positive solutions for a discrete non-liner third-order boundary value problem, which has the sign-changing Green's function. The approach we use is the fixed point theorem in cone.
