Abstract: In this paper we present a simpler method of proving the correctness and selfadjointtness of the operators of the form $B^2$ corresponding to some boundary value problems. We also give explict representations for the unique solution of these problems.

Keywords and phrases: correct operators, selfadjoint operators, boundary value problems.
