- Abstract
- In this paper, we prove the Hyers-Ulam-Rassias stability of the following additive functional inequality: (0.1) parallel to f(2x) + f(2y) + 2f(z)parallel to <= parallel to 2f(x + y + z)parallel to. We investigate homomorphisrns in proper CQ*-algebras and derivations on proper CQ*-algebras associated with the additive functional inequality (0.1).
