In this paper, we investigate the existence of positive solitions for nonlinear four-order m-point boundary value problem {u(4)(t) = λh(t)f(t,u), 0<;t<;1, β1u(0) - γ1u\´(0) = 0, u(1) = Σi=1m-2 aiu(ξi), β2u"(0)-γ2u\´"(0)=0 u"(1)=Σi=1m-2 biu"(ξi), where the nonlinear term f is allowed to change sign.
