摘要:

基于泛函形式的锥拉伸与锥压缩不动点定理, 本文获得了一类四阶梁方程边值问题正解的存在性. 与已有文献不同的是本文所研究的方程的非线性项依赖于所有低阶导数.

关键词: 四阶边值问题, 不动点定理, 正解

Abstract:

This paper addresses the existence of positive solutions for a type of fourth-order beam equation boundary value problems based on function-typed fixed point theorem of cone expansion and compression. The unique characteristic is that its nonlinear term depends on all lower-order derivatives.

Key words: fourth-order boundary value problem, fixed point theorem, positive solution
