Approximation of homomorphisms and derivations on Lie C*- algebras via fixed point method

Abstract

In this paper, using fixed point methods, we prove the generalized Hyers-Ulam stability of homomorphisms in C*-algebras and Lie C*-algebras and of derivations on C*-algebras and Lie C*-algebras for an m-variable additive functional equation. © 2013 Cho et al.; licensee Springer.
