摘    要:本文讨论二阶微分方程两点边值问题解的存在性.在不限制f∈C(0,1]×R^2,R)增长,但满足一定符号条件的前提下,应用Leray-Schauder度原理中的一个不动点定理,证明了上述边值问题解的存在性.

关 键 词:二阶两点边值问题  解的存在性  Leray-Schauder度原理  符号条件

Abstract:This paper is concerned with existence of solutions of second order differential equations for two -point boundary value problem: x'' = f(t, x, x' ) ,0 〈 x 〈 1, x (0) = x' ( 1 ) = 0. On the bases of not limiting the growth of f ∈ C( 0,1 ] × R^2, R)and meeting the needs of some symbol conditions, by using Leray- Schauder's fixed point theorem, the authors obtain existence of solutions of above problem.
Keywords:second-order two point boundary value problem  existence of solutions  Leray-Schauder degree principle  symbol condition
