A note on generalized (m,n)-Jordan centralizers [PDF]

open access: yes, 2013
The aim of this paper is to define generalized ▫$(m, n)$▫-Jordan centralizers and to prove that on a prime ring with nonzero center and ▫${rm char}(R) ne 6mn(m+n)(m+2n)$▫ every generalized ▫$(m, n)$▫-Jordan centralizer is a two-sided centralizer.V članku

Generalized derivations on ideals of prime rings

open access: yes, 2013
Let R be a prime ring. By a generalized derivation we mean an additive mapping g W R! R such that g.xy/D g.x/yCxd.y/ for all x;y 2 R where d is a derivation of R.

On zero subrings and periodic subrings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 28, Issue 7, Page 413-417, 2001., 2001
We give new proofs of two theorems on rings in which every zero subring is finite; and we apply these theorems to obtain a necessary and sufficient condition for an infinite ring with periodic additive group to have an infinite periodic subring.

On Ideals and Orthogonal Generalized Derivations of Semiprime Rings [PDF]

open access: yes, 2007
In this paper, some results concerning orthogonal generalized derivations are generalized for a nonzero ideal of a semiprime ring. These results are a generalization of results of M. Brešar and J.

A note on centralizers

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 1, Page 55-57, 2000., 2000
For prime rings R, we characterize the set U∩CR([U, U]), where U is a right ideal of R; and we apply our result to obtain a commutativity‐or‐finiteness theorem. We include extensions to semiprime rings.

On Commutativity of Rings with Generalized Derivations [PDF]

open access: yes, 2002
The concept of derivations as well as of generalized inner derivations have been generalized as an additive function F : R → R satisfying F(xy) = F(x)y + xd(y) for all x, y ∈ R, where d is a derivation on R, such a function F is said to be a ...

Derivations of higher order in semiprime rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 21, Issue 1, Page 89-92, 1998., 1997
Let R be a 2‐torsion free semiprime ring with derivation d. Supposed d2n is a derivation of R, where n is a positive integer. It is shown that if R is (4n − 2)‐torsion free or if R is an inner derivation of R, then d2n−1 = 0.

Commutativity results for semiprime rings with derivations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 21, Issue 3, Page 471-474, 1998., 1996
We extend a result of Herstein concerning a derivation d on a prime ring R satisfying [d(x), d(y)] = 0 for all x, y ∈ R, to the case of semiprime rings. An extension of this result is proved for a two‐sided ideal but is shown to be not true for a one‐sided ideal.
