摘要
In this paper, we discuss the existence of positive solutions to the following fractional boundary value problem with changing sign nonlinearity. {D(0+)(alpha)u(t) + lambda f(t, u(t)) = 0, 0 < t < 1, u(0) = u'(0) = u(1) = 0, where 2 < alpha <= 3 is a real number, D(0+)(alpha) is the standard Riemann-Liouville derivative, lambda is a positive parameter, f may change sign and may be singular at t = 0, 1.
