چکیده
where D+ is the standard Caputo derivative with < α ≤ and δ, γ are constants with δ > , γ > . Differential equations of fractional order have recently proved to be valuable tools in the modeling of many phenomena in various fields of science and engineering. Indeed, we can findnumerous applications in viscoelasticity, electrochemistry, control, porousmedia, electromagnetism, etc. (see [–]). There has been a significant development in the study of fractional differential equations and inclusions in recent years, see the monographs of Podlubny [], Kilbas et al. [], Lakshmikantham et al. [], Samko et al. [], Diethelm [],

In this paper, we study sufficient conditions for existence and uniqueness of solutions of three point boundary vale problem for p-Laplacian fractional order differential equations. We use Schauder's fixed point theorem for existence of solutions and concavity of the operator for uniqueness of solution. We include some examples to show the applicability of our results.
