  • Abstract
    The paper is devoted to the study a regular solvability of some boundary value problems for a fourth order operator-differential equations on a finite segment. Using the theorem on the estimations of inter mediate derivatives, sufficient conditions for regular solvability of the given problem are obtained. Sufficient conditions for regular solvability of a boundary value problem are expressed by means of the norms of the operators of intermediate derivatives.
