A boundary value problem given by multi-point conditions is investigated for a fourth-order differential equation. A system of five integro-algebraic equations called as an adjoint system is introduced for this problem. A Green's functional concept is introduced as a special solution of the adjoint system. This new type of Green's function concept, which is more natural than the classical Green-type function concept, and an integral form of the nonhomogeneous problems can be found more naturally.
