$$ -Lie-type maps on $C^{}$ -algebras

Ruth Nascimento Ferreira, Bruno Leonardo Macedo Ferreira, Henrique Guzzo Junior +1

Let $A$ and $A^{'}$ be two $C^{*}$ -algebras with identities $I_{A}$ and $I_{A^{'}}$ , respectively, and $P_{1}$ and $P_{2} = I_{A} - P_{1}$ …

Additivity of $n$ -Multiplicative Mappings of Gamma Rings

Aline Jaqueline de Oliveira Andrade, Gabriela Cotrim de Moraes, Ruth Nascimento Ferreira +1

In this paper, we address the additivity of $n$ -multiplicative isomorphisms and $n$ -multiplicative derivations on Gamma rings. We proved that, if $\M$ is a $Γ$ -ring satisfying the…

Nonlinear $$ -Jordan-type derivations on alternative $$ -algebras

Aline Jaqueline de Oliveira Andrade, Gabriela C. Moraes, Ruth Nascimento Ferreira +1

Let $A$ be an unital alternative $*$ -algebra. Assume that $A$ contains a nontrivial symmetric idempotent element $e$ which satisfies $x A \cdot e = 0$ implies $x = 0$ and $xA \cdot…

Generalized Jordan derivations of Incidence Algebras

Bruno Leonardo Macedo Ferreira, Tanise Carnieri Pierin, Ruth Nascimento Ferreira

For a given ring $R$ and a locally finite pre-ordered set $(X, \leq)$ , consider $I (X, R)$ to be the incidence algebra of $X$ over $R$ . Motivated by…

Generalized Jordan derivations on semiprime rings

Bruno L M Ferreira, Henrique Guzzo, Ruth N. Ferreira

The purpose of this note is to prove the following. Suppose $R$ is a semiprime unity ring having an idempotent element e $(e \neq = 0, e \neq = 1)$ which satisfies mild con…

An approach between the multiplicative and additive structure of a Jordan ring

Bruno Ferreira

Let J and J' be Jordan rings. We prove under some conditions that if J contains a nontrivial idempotent, then n-multiplicative maps and n-multiplicative derivations from J to J' ar…
