Volume 33 • Number 2 • 2010   • On a Cauchy-Jensen Functional Inequality Abbas Najati, Jung-Rye Lee and Choonkil Park Abstract. In this paper, we investigate the following functional inequality in Banach modules over a C*-algebra, and prove the generalized Hyers-Ulam stability of additive mappings in Banach modules over a C*-algebra to approximate homomorphisms. 2000 Mathematics Subject Classification: Primary: 39B72; Secondary: 46L05.
