We apply this technique to a higher order linear ODE involving general nonlocal conditions. A novel kind of adjoint problem and Green’s functional are constructed for the completely inhomogeneous problem. Several illustrative applications of the theoretical results are provided.}, number={1}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={Özen, K.}, year={2019}, month={Jan.}, pages={99-116} }
