摘要: 用Leray-Schauder不动点定理, 讨论四阶边值问题的可解性. 在允许非线性项f(x,u,v)关于u,v超线性增长的条件下, 获得了该问题解的存在性和唯一性结果.

关键词: 弹性梁方程, 存在唯一性, 超线性增长, Leray-Schauder不动点定理

Abstract: By using the Leray-Schauder fixed point theorem, we discuss the solvability of the fourth-order boundary value problem.  The existence and uniqueness of solutions to the problem are obtained under the condition that the nonlinear term f(x,u,v) is allowed to grow superlinearly with respect to  u,v.

Key words: elastic beam equation, existence and uniqueness, superlinear growth, Leray-Schauder fixed point theorem
