In this paper, the authors consider the following fractional high-order three-point boundary value problem: D(0+)(alpha)u(t) + f(t, u(t)) = 0, t is an element of (0, 1), u(0) = u'(0) = ... = u((n-2))(0) = 0, D(0+)(alpha-1)u(eta) = kD(0+)(alpha-1)u(1), where k > 1, eta is an element of (0, 1), n - 1 < alpha <= n, n >= 3, D-0+(alpha) is the standard Riemann-Liouville derivative of order alpha, and f : [0, 1] x [0,+infinity) -> [0,+infinity) is continuous. By using some fixedpointindextheorems on a cone for differentiableoperators, the authors obtain the existence of positive solutions to the above boundary value problem.
