摘要
In this paper, we study the existence of positive solutions to the nonlinear fractional order singular and semipositone nonlocal boundary value problem {D-0(alpha) u(t) + f(t, u(t)) = 0, 0 < t < 1, u(0) = u'(0) = .... = u((n-2)) (0) = 0, u(1) = mu integral(1)(0) u(s)ds by using the Leray-Schauder nonlinear alternative and a fixed-point theorem on cones, where 0 < mu < alpha, 2 <= n-1 < alpha <= n, D-0(alpha)+ is the standard Riemann-Liouville derivative, and f(t,u) is semipositone and may be singular at u = 0.
