Query: On complements and the factorization problem for Hopf algebras   Two new results concerning complements in a semisimple Hopf algebra are
proved. They extend some well known results from group theory. The uniqueness
of Krull Schmidt Remak type decomposition is proved for semisimple completely
reducible Hopf algebras.
