摘要
In this paper, we discuss the existence and uniqueness of a positive solution to the following singular fractional differential equation with nonlocal boundary value conditions: {D(0+)(alpha)u(t) + f(t, u(t)) = 0, 0 < t < 1, u(0) = 0, D(0+)(beta)u(1) = Sigma(m-2)(i=1) eta(i)D(0+)(beta)u(xi(i)), where 1 < alpha <= 2, 0 < beta < alpha - 1, 0 < xi(1) < ... < xi(m-2) < 1 with Sigma(m-2)(i=1) eta(i)xi(alpha-beta-1)(i) < 1, D-0+(alpha) is the standard Riemann-Liouville derivative, f may be singular at t = 0, t = 1, u = 0.
