Continuity of derivations on \(H^*\)-algebras. (English) Zbl 0822.46061
Summary: We prove that the separating subspace for a derivation of a nonassociative \(H^*\)-algebra is contained in the annihilator of the algebra. In particular, derivations on nonassociative \(H^*\)-algebras with zero annihilator are continuous.
