On multiplicative centrally-extended maps on semi-prime rings.

In this paper, we show that for semi-prime rings of two-torsion free and 6-centrally torsion free, given a multiplicative centrally-extended derivation δ and a multiplicative centrally-extended epimorphism ϕ we can find a central ideal K and maps Δ , Φ : S / K → S / K such as Δ and Φ are multiplicative derivation and multiplicative epimorphism, respectively.
