摘要
利用Sadovskii不动点定理,讨论了Banach空间中的二阶常微分方程的一类n点边值问题,得到了至少一个解的存在性件。作为应用,给出了一个无限维空间中的例子。
The boundary value problems(BVPs)have become a focus.But in Banach spaces,as far as the-point BVPS are concerned,there are few results.By using the Sadovskii fixed point theorem,the second-order n-point BVP in a Banach space is studied,the existence of at least one solution is obtained.As an application,an example in an infinite dimensional space is also given to demonstrate the results.
