Commutativity of Prime Gamma Rings with Left Centralizers
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)

A characterization of jordan left ∗ -centralizers via skew lie and jordan products
WOS:000744369500001Let n≥ 1 be a fixed integer and R be a ring with involution ‘∗ ’. For any two elements x and y in R, the n-skew Lie product and n-skew Jordan product are given by ▿ [x, y] n= ▿ [x, ▿ [x, y] n-1] with ▿[x,y]0=y,▿[x,y]1=▿[x,y]=xy-yx∗,▿[x,

Characterization of prime rings having involution and centralizers
The major goal of this paper is to study the commutativity of prime rings with involution that meet specific identities using left centralizers. The results obtained in this paper are the generalization of many known theorems.

Central Extension of Left Alternative Algebras and the Second Cohomology Group [PDF]
The purpose of this paper is to prove that the second cohomology group of a left alternative algebra A over an algebraically closed field of characteristic 0 can be interpreted as the set of equivalent classes of one‐dimensional central extensions of A.

On ?-centralizers of semiprime rings
Let R be a semiprime 2-torsion free ring, and let ? be an endomorphism of R. Under some conditions we prove that a left Jordan ?-centralizer of R is a left ?-centralizer of R. Under the same conditions we also prove that a Jordan ?-centralizer of R is a ?

Free actions on semiprime rings [PDF]
summary:We identify some situations where mappings related to left centralizers, derivations and generalized $(\alpha ,\beta )$-derivations are free actions on semiprime rings. We show that for a left centralizer, or a derivation $T$, of a semiprime ring

ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Nilpotency in groups with the minimal condition on centralizers
The Sylow-2-subgroups of a periodic group with minimal condition on centralizers are locally finite and conjugate. The same holds for the Sylow-p-subgroups for any prime p, provided the subgroups generated by any two p-elements of the group are finite ...

ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...
