J. Math. Sci., New York 168, No. 3, 420-427 (2010); translation from Zap. Nauchn. Semin. POMI 373, 194-209 (2009).
Summary: In this paper, we present a simple method to prove the correctness and self-adjointness of operators $$B^3$$ corresponding to some boundary value problems. We also give the unique solutions for these problems. The algorithm is easy to implement via computer algebra systems. In our examples, Derive and Mathematica were used.
