In this paper,we consider the fractional multi-point boundary value problem. By Leggett-Williams fixed point theorem,sufficient conditions that guarantee the existence of three positive solutions are obtained.
Using a fixed point theorem,this paper discusses the existence and uniqueness of positive solutions to a system of nonlinear delay fractional differential equations and obtains some new results.
