| Abstract: | In this paper, we consider the existence of positive solutions for fractional with integral boundary conditions. First, we give the properties of Green＇s function. boundary value problems Second, the problem has been reduced to the equivalent Fredholm integral equation. Finally, using Krasnoselkii fixed point theorem and Leggett-Williams fixed point theorem, some results on the existence of positive solutions are obtained. The work is an extension of the previous results |
