In any case, when R is a prime ring, all that we need here about this object is that
In , Ashraf and Rehman established that a prime ring R with a nonzero ideal I must be commutative, if R admits a nonzero derivation d satisfying d(xy) + xy [member of] Z(R) for all x,y [member of] I or d(xy) - xy [member of] Z(R) for all x,y [member of] I.
A well known result of Posner (19) states that for a non-zero derivation d of a prime ring R, if [[d(x), x], y] = 0 for all x, y [member of] R, then R is commutative.

In  Bell and Kappe proved that if d is a derivation of a prime ring R which acts as a homomorphism or as an anti-homomorphism on a nonzero right ideal I of R, then d = 0 on R.
Let R be a prime ring of characteristic [not equal to] 2 with right quotient ring U and extended centroid C, g [not equal to] 0 a generalized derivation of R, L a non-central Lie ideal of R and n [greater than or equal to] 1 such that [g(u), u][.

Let R be a prime ring of characteristic different from 2, d a non-zero derivation of R and I a non-zero right ideal of R such that [d(x)[x.
They include discussions of the Galois map and its induced maps, when direct sums of modules inherit certain properties, prime rings with left derivations, some commutativity theorems concerning additive mappings and derivations on semi-prime rings, a short proof that continuous modules are clean, and imprimitive regular action in the ring of integers modulo n.
