讨论三阶三点非齐次边值问题{u″′(t)+a(t)f(u(t))=0,0
The third-order three-point nonhomogeneous boundary value problemu″ ′ (t)+a(t)f(u(t))=0,0t1u(0)=u′(0)=0,u′(1)-αu′(η)=λis considered in this paper,where η∈(0,1),α∈[0,1/η) and λ∈(0,+∞) are some parameters.By using Guo-Krasnosel'skii fixed-point theorem,the new existence results of two positive solutions are obtained.
