Popis: This article is devoted to the study of the parameter's set where the Green's function related to a general linear nth-order operator, depending on a real parameter, T_n[M], coupled with many different two point boundary value conditions, is of constant sign. This constant sign is equivalent to the strongly inverse positive (negative) character of the related operator on suitable spaces related to the boundary conditions.
