Abstract
Using the Hyers-Ulam-Rassias stability method, we investigate isomorphisms
in Banach algebras and derivations on Banach algebras associated with
the following generalized additive functional inequality
ǁaf(x) + bf(y) + cf(z)ǁ ≤ ǁf(αx + βy + Υ
z)ǁ. (0.1)
Moreover, we prove the Hyers-Ulam-Rassias stability of homomorphisms in Banach
algebras and of derivations on Banach algebras associated with the generalized
additive functional inequality (0.1).
Keywords
