摘要
This paper studies a nonlinear three-point boundary value problem of sequential fractional differential equations of order alpha + 1 with 1 < alpha <= 2. The expression for Green's function of the associated problem involving the classical gamma function and the generalized incomplete gamma function is obtained. Some existence results are obtained by means of Banach's contraction mapping principle and Krasnoselskii's fixed point theorem. An illustrative example is also presented. Existence results for a three-point third-order nonlocal boundary value problem of nonlinear ordinary differential equations follow as a special case of our results. (C) 2012 Elsevier Ltd.
