摘要
考虑如下m点边值问题解的存在性:u″=f(t,u,u′)+e(t)(0<t<1)u(0)=0,u(1)=∑m-2i=1aiu(ξi)其中:f:[0,1]×R2→R连续;e(t)∈C[0,1];ai>0,i=1,2,…,m-2;0<ξ1<ξ2<…<ξm-2<1;∑m-2i=1aiξi≠1.通过对一族边值问题解的先验估计,利用Leray-Shauder连续性定理,得到解的存在性.
This paper is concerned with the problem of existence of a solution for m - points boundary value problem :
u″=f(t,u,u′)+e(t) (0〈t〈1)
u(0)=0,u(1)=^m-2∑i=1 αiu(ζi)
The existence theorems of the solution be obtained by using Leray - Shauder continuous theorem under some conditions.
