Existence of three non-negative solutions for a three-point boundary-value problem of nonlinear fractional differential equations

Electronic Journal of Differential Equations, 2012
This article concerns the existence of three non-negative solutions for two kinds of three-point boundary-value problems of nonlinear fractional differential equations, where the fractional derivative is taken in the Riemann-Liouville sense.
