摘要
运用锥上的Guo-Krasnoselskii’s不动点定理证明了变号二阶三点边值问题u″+h(t)f(u(t))=0,t∈[0,1],u(0)=αu(η),u(1)=βu(η)至少一个正解的存在性.
The existence of at least one positive solution for a knind of second-order three-point boundary value problem u″+h(t)f(u(t))=0,t∈[0,1],u(0)=αu(η),u(1)=βu(η) was investigated by the well-known Guo- Krasnoselskii' s fixed-point theorem in cones.
