Abstract: In order to study three-point BVPs for fourth-order impulsive differential equation of the form(\phip(u''(t)))''- f(t,u(t))=0, t≠ ti,△ u(ti)=-Ii(u(ti)), i=1, 2, ..., k,△u'(ti)=-Li(u(ti)), i=1, 2, ..., k,(\star)with the following boundary conditionsu'(0)=u(1)=0, u''(0)=0=u''(1)-\phiq(α)u''(η),the authors translate the fourth-order impulsive differential equations with p-Laplacian (\star) into three-point BVPs for second-order differential equation without impulses and two-point BVPs for second-order impulsive differential equation by a variable transform. Based on it, existence theorems of positive solutions for the boundary value problems (\star) are obtained.

Key words: Impulsive differential equation, BVP, P-Laplacian, Variable transform
