Stability and hyperstability of multi-additive-cubic mappings
Ahmad Nejati; Abasalt Bodaghi; Ayoub Gharibkhajeh;Abstract
In this article, we unify the system of functional equations defining a multi additive-cubic mapping to obtain a single equation. Using a fixed point theorem, we study the generalized Hyers-Ulam stability of such equation. As a result, we show that the multi-additive-cubic functional equation is hyperstable.
