초록

We investigate homomorphisms in proper JCQ*-triples and derivations on proper JCQ*-triples associated with the 3-variable Jensen functional equation 2f(x+y+z/2)= f(x)+f(y)+f(z), which was introduced and investigated by Park, Cho and Han. We moreover prove the Hyers?Ulam?Rassias stability of homomorphisms in proper JCQ*-triples and of derivations on proper JCQ*-triples. This is applied to investigate isomorphisms between proper JCQ*-triples.
