In this paper we prove that on a 2-torsion free semiprime ring R every Jordan triple (resp. generalized Jordan triple) derivation on Lie ideal L is a derivation on L (resp. generalized derivation on L ).

An additive mapping F: R → R is called a generalized derivation on R if there exists a derivation d: R → R such that F(xy) = xF(y) + d(x)y holds for all x,y ∈ R. It is called a generalized (α,β)−derivation on R if there exists an (α,β)−derivation d: R → R such that the equation F(xy) = F(x)α(y)+β(x)d(y) holds for all x,y ∈ R. In the present paper, we investigate commutativity of a prime ring R, which satisfies certain differential identities on left ideals of R. Moreover some results on commutativity of rings with involutions that satisfy certain identities are proved.
Let R be a prime ring with center Z ( R ). A map G : R → R is called a multiplicative (generalized) ( α , β )-derivation if G ( xy )= G ( x ) α ( y )+ β ( x ) g ( y ) is fulfilled for all x ; y ∈ R , where g : R → R is any map (not necessarily derivation) and α ; β : R → R are automorphisms. Suppose that G and H are two multiplicative (generalized) ( α , β )-derivations associated with the mappings g and h , respectively, on R and α , β are automorphisms of R . The main objective of the present paper is to investigate the following algebraic identities: ( i ) G ( xy ) + α ( xy ) = 0, ( ii ) G ( xy ) + α ( yx ) = 0, ( iii ) G ( xy ) + G ( x ) G ( y ) = 0, ( iv ) G ( xy ) = α ( y ) ○ H ( x ) and ( v ) G ( xy ) = [ α ( y ), H ( x )] for all x , y in an appropriate subset of R .
The purpose of this article is to enhance the previous studies regarding the behavior of a quotient ring , where ℘ is a prime ideal in a ring ℑ. In particular, we are going to explore more general scenarios whenever a ring ℑ admits a generalized -derivation associated with an -derivation ∂ that satisfies certain criteria involving ℘, where and are automorphisms on ℑ. Moreover, we provide some examples to demonstrate the importance of the assumptions made in our results.
The current article focuses on studying the behavior of a ring when ℜ admits generalized derivations and with associated derivations and , respectively. These derivations satisfy specific differential identities involving , where is a prime ideal of an arbitrary ring ℜ, not necessarily prime or semiprime. Furthermore, we explore some consequences of our findings. To emphasize the necessity of the primeness of in the hypotheses of our various theorems, we provide a list of examples.
