标题：Properties of positive solutions for the operator equation A x = λ x $Ax=\lambda x$ and applications to fractional differential equations with integral boundary conditions
摘要：In this article we present a new fixed point theorem for a class of generalized concave operators and we establish some properties of positive solutions for the operator equation A x = λ x $Ax=\lambda x$ . Based on them, the existence and uniqueness of positive solutions for a class of fractional differential equations with integral boundary conditions is proved. Moreover, we present some properties of positive solutions to the boundary value problem dependent on the parameter.
