Abstract
In this paper, we investigate homomorphisms in proper CQ*-algebras, proper Lie CQ*-algebras and proper Jordan CQ*-algebras and derivations on proper CQ*-algebras, proper Lie CQ*-algebras and proper Jordan CQ*-algebras associated with the Cauchy-Jensen functional equation 2f (x+y/2 + z) = f (x) + f (y) + 2f (z), which was introduced and investigated in [3,28]. Furthermore, Isometrics and isometric isomorphisms in proper CQ*-algebras are studied.
