Abstract

This paper aims to establish the following: Let $ \Omega $ be a ring that satisfies some conditions and has an idempotent element $ f\neq 0, 1 $. We intend to show that if $ G $ is any suitable multiplicative generalized CE-derivation of $ \Omega $, then $ G $ is a centrally extended additive.
