We characterize generalized Lie derivations on skew elements of prime algebras A with involution, provided that A does not satisfy polynomial identities of low degree. The analogous result for matrix algebras is also described.
Let A be an absolute valued algebra with involution, in the sense of Urbanik [K. Urbanik, Absolute valued algebras with an involution, Fund. Math. 49 (1961) 247-258]. We prove that A is finite-dimensional if and only if the algebra obtained by symmetrizing the product of A is simple, if and only if
## Abstract It is shown that derivations on LMC\*βalgebras are always continuous and generate a continuous oneβparameter group of automorphisms. The structure of the derivation and the automorphism group on LMC\*βalgebras is investigated.
