Multiplicativity of left centralizers forcing additivity

open access: diamondBoletim da Sociedade Paranaense de Matemática, 2014
A multiplicative left centralizer for an associative ring R is a map satisfying T(xy) = T\(x)y for all x,y in R. T is not assumed to be additive. In this paper we deal with the additivity of the multiplicative left centralizers in a ring which contains ...

The lattice of left ideals in a centralizer near-ring is distributive [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1982
A decomposition theorem for a left ideal in a finite centralizer near-ring is established. This result is used to show that the lattice of left ideals in a finite centralizer near-ring is distributive.

Left centralizers and isomorphisms of group algebras [PDF]

open access: bronzePacific Journal of Mathematics, 1952
The principal result (Theorem 1) of Part I states that, conversely, every left centralizer is a convolution with a regular measure. Important auxiliary theorems (3 and 4) furnish a characterization of the right translations (up to scalar factors of unit modulus), and show that in the strong operator topology any left centralizer may be approximated by ...

On Left s -Centralizers Of Jordan Ideals And Generalized Jordan Left (s ,t ) -Derivations Of Prime Rings [PDF]

open access: diamondEngineering and Technology Journal, 2011
In this paper we generalize the result of S. Ali and C. Heatinger on left s - centralizer of semiprime ring to Jordan ideal, we proved that if R is a 2-torsion free prime ring, U is a Jordan ideal of R and G is an additive mapping from R into itself ...

Left centralizers on rings that are not semiprime

open access: hybridRocky Mountain Journal of Mathematics, 2011
A (left) centralizer for an associative ring R is an additive map satisfying T(xy) = T(x)y for all x , y in R . A (left) Jordan centralizer for an associative ring R is an additive map satisfying T ( xy + yx ) = T ( x ) y + T ( y ) x for all x , y in R . We characterize rings with a Jordan centralizer T .

Commutativity of Prime Gamma Rings with Left Centralizers

open access: goldJournal of Scientific Research, 2013
Let M be a G-ring. If M satisfies the condition (*) xaybz = xbyaz for all x, y, zÎM, a, bÎG, then we investigate commutativity of prime G-rings satisfying certain identities involving left centralizer. Keywords: Prime G-ring; Derivation; Generalized derivation; Left centralizer. © 2014 JSR Publications. ISSN: 2070-0237 (Print); 2070-0245 (Online)

Left centralizers of an $H\sp{\ast} $-algebra [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1974
An explicit characterization is given of the left centralizers of a proper H*-algebra A. Each left centralizer is seen to correspond to a bounded family of bounded operators, where each operator acts on a Hilbert space associated with a minimalclosed two-sided ideal of A. Introduction. Let A be a semisimple Banach algebra.

On Left Centralizers of Semiprime Γ-Rings

open access: goldJournal of Scientific Research, 2012
Let M be a semiprime G-ring satisfying an assumption   xaybz = xbyaz for all x, y, z?M, a, b?G. In this paper, we prove that a mapping T: M ? M is a centralizer if and only if it is a centralizing left centralizer. We also show that if T and S are left centralizers of M such that T(x)a x + x a S(x)?Z(M) (the center of M) for all x?M, a?G, then both T ...

A note on Jordan left *-centralizers in rings with involution

open access: closedInternational Journal of Algebra, 2015
Let R be a ring with involution. An additive mapping T : R → R is called a left ∗-centralizer (resp. Jordan left ∗-centralizer) if T (xy) = T (x)y∗ (resp.
