A unified approach to some two-point, three-point, and four-point boundary value problems with Carathéodory functions
The paper, that is a sequel of the first seven references quoted, deals with a unified approach to some two-point, three-point and four-point boundary value problem with Carathéodory functions. The main theorem is proved on the basis of four lemmas.
