 Stability of homomorphisms and derivations in proper $JCQ^{*}$-triples associated to the Pexiderized Cauchy type mapping Bull. Korean Math. Soc. 2009 Vol. 46, No. 1, 45-60 Printed January 1, 2009 Abbas Najati, G. Zamani Eskandani, and Choonkil Park University of Mohaghegh Ardabili, University of Tabriz, and Hanyang University Abstract : In this paper, we investigate homomorphisms in proper $JCQ^{*}$-triples and derivations on proper $JCQ^{*}$-triples associated to the following Pexiderized functional equation $f(x+y+z) = f_{0} (x)+ f_{1} (y) +f_{2} (z).$ This is applied to investigate homomorphisms and derivations in proper $JCQ^{*}$-triples. Keywords : generalized Hyers--Ulam stability, proper $JCQ^{*}$-triples homomorphism, proper $JCQ^{*}$-triples derivation MSC numbers : Primary 39B52, 47N50, 47L60, 47L90, 46H35, 46B03 Downloads: Full-text PDF
