On centralizers of prime rings with involution
Let $R$ be a ring with involution $*$. An additive mapping $T:Rto R$ is called a left(respectively right) centralizer if $T(xy)=T(x)y$ (respectively $T(xy)=xT(y)$) for all $x,yin R$. The purpose of this paper is to examine the commutativity of prime rings with involution satisfying certain identities involving left centralizers.
متن کاملEquations in free semigroups with involution and their relation to equations in free groups
A free semigroup with involution (FSI) is essentially the set of words over a given alphabet plus an operator which reverses words. The paper introduces equations in FSI and show that they are the right objects to deal with when studying the complexity of equations in free groups. On these lines, we generalize to FSI several results valid for word equations, like the overlapping lemma, the 2O(|...
متن کاملEquations in Free Semigroups with Anti-involution and Their Relation to Equations in Free Groups
The main result of the paper is the reduction of the problem of satisfiability of equations in free groups to the satisfiability of equations in free semigroups with anti-involution (SGA), by a non-deterministic polynomial time transformation. A free SGA is essentially the set of words over a given alphabet plus an operator which reverses words. We study equations in free SGA, generalizing seve...

let $r$ be a ring with involution $*$. an additive mapping $t:rto r$ is called a left(respectively right) centralizer if $t(xy)=t(x)y$ (respectively $t(xy)=xt(y)$) for all $x,yin r$. the purpose of this paper is to examine the commutativity of prime rings with involution satisfying certain identities involving left centralizers.
متن کامل2-local Mappings on Algebras with Involution
We investigate 2-local ∗-automorphisms, 2-local ∗-antiautomorphisms, and 2-local Jordan ∗-derivations on certain algebras with involution.
