Abstract
This paper studies a coupled system of nonlinear fractional differential equations with three-point boundary conditions. Applying the Schauder fixed point theorem, an existence result is proved for the following system
D(alpha)u(t) = f(t, nu(t), D-p nu(t)), D-beta nu(t) = g(t, u(t), D(q)u(t)), t is an element of (0, 1),
u(0) = 0, u(1) = gamma u(eta), nu(0) = 0, nu(1) = gamma nu(eta)
where alpha, beta, p, q, eta, gamma satisfy certain conditions. (C) 2009 Elsevier Ltd. All rights reserved.
