摘要:In this paper, we consider a four-point coupled boundary value problem for system of the nonlinear semipositone fractional differential equation ,,, where the coefficients are real positive constants, , are the standard Riemann-Liouville derivatives. Values of the parameters and are determined for which boundary value problem has positive solution by utilizing a fixed point theorem on cone.
