| Abstract: | In this paper,we mainly study the existence and the existence and uniqueness of positive solutions for a class of two-term fractional differential equations with integral boundary value problem under different conditions.By the Schauder fixed point theorem combined with the method of upper and lower solutions,the existence of positive solution is found out.We also obtain the existence and uniqueness of the positive solution by using Banach contraction mapping principle.And two examples are given to show the applicability of the results in this paper. |
