Existence of Positive Solution for Third-Order Three-Point Boundary Value Problems
摘要
Abstract
We study the existence of positive solution to the following third-order three-point boundary value problems u(t)+a(t)f(u(t))= 0 ,t∈(0 ,1 ),u(0 )= u′(0 )= 0 ,u′(1 )-αu′(η)=λ,where 0<η<1 ,0<α<1/η,λ>0.By using fixed point theorem in cones,we obtain the existence of the positive solution if f is either superlinear or sublinear.Our results extend and improve some results made by Wu Hongping.关键词
