AB - Let h ∈ L¹[0,1] ∩ C(0,1) be nonnegative and f(t,u,v) + h(t) ≥ 0. We study the existence and multiplicity of positive solutions for the nonlinear fourth-order two-point boundary value problem
$u^{(4)}(t) = f(t,u(t),u^{\prime }(t))$, 0 < t < 1, u(0) = u’(0) = u’(1) =u”’(1) =0,
where the nonlinear term f(t,u,v) may be singular at t=0 and t=1.
