A FIXED POINT APPROACH TO THE STABILITY OF THE FUNCTIONAL EQUATIONS RELATED TO AN ADDITIVE AND QUARTIC MAPPING

Sun-Sook Jin, Yang-Hi Lee

Abstract


In this paper, we prove the stability of functional equations related to an additivequartic mapping by using the fixed-point theory, which L. C adariu and V. Radu used as away to prove the stability of functional equations.
