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

Abstract

Using fixed point methods, we prove the generalized Hyers-Ulam stability of homomorphisms in C*-algebras and Lie C*-algebras and of derivations on non-Archimedean C*-algebras and Non-Archimedean Lie C*-algebras for an m -variable additive functional equation. Copyright © 2012 Yeol Je Cho et al.
