Existence of Three Positive Solutions for Second-order Multipoint Boundary Value Problems with Delay

研究具有时滞的二阶多点边值问题,应用Avery和Peterson推广的Leggett-Williams不动点定理,给出了该边值问题至少存在3个正解的充分条件。

This paper is concerned with the second-order muhipoint boundary value problems with delay. By using a generalization of Leggett-Williams fixed-point theorem due to Avery and Peterson,we provide sufficient conditions for the existence of at least three positive solutions to the boundary value problems.
