Bogoyavlenskii proposed for symmetric operators a construction connected with filtrations of Lie algebras, for which the Euler equations have a large set of integrals. In this article integrability in the Liouville sense is proved for the Euler equations on a semisimple Lie algebra with symmetric operator constructed from a filtration of Lie algebras that is connected with a chain of involution automorphisms. Bibliography: 9 titles.
