摘要
证明了四阶非线性特征值问题y(4) - λa(x) f(y(x) ) =0 0 <x<1y(0 ) =y(1 ) =y″(0 ) =y″(1 ) =0正解的存在性。主要工具是 Krasnoselskii不动点定理。
The existence of positive solutions of fourth\|order nonlinear eigenvalue problem is proved by using Krasnoselskii fixed point theorem. y\+\{(4)\}-λa(x)f(y(x))=0\ 0<x<1 y(0)=y(1)=y″(0)=y″(1)=0
