Let $\mathfrak{A}$ and $\mathfrak{A}'$ be two $C^*$-algebras with identities $I_{\mathfrak{A}}$ and $I_{\mathfrak{A}'}$, respectively, and $P_1$ and $P_2 = I_{\mathfrak{A}} - P_1$ nontrivial symmetric projections in $\mathfrak{A}$. In this paper we s

Motivated by the recent progress towards classification of simple finite-dimensional Lie algebras over an algebraically closed field of characteristic 2, we investigate such 15-dimensional Skryabin algebras.

Let $${{\mathfrak {J}}}\, $$ and $${{\mathfrak {J}}}\, ^{'}$$ be Jordan rings. In this paper we study the additivity of n-multiplicative isomorphisms from $${{\mathfrak {J}}}\, $$ onto $${{\mathfrak {J}}}\, ^{'}$$ and of n-multiplicative derivations

não disponível In the first part of this monograph, we introduce the concept of join of baric algebras with an idempotent of weight 1 and the related concept of indecomposable (baric) algebra. A theorem of existence and unicity of decompositions fo

The purpose of this note is to prove the following. Suppose $\R$ is a semiprime unity ring having an idempotent element e $\left(e \neq 0, e \neq 1\right)$ which satisfies mild conditions. It is shown that every additive generalized Jordan derivation

Let $\R$ be an alternative ring containing a nontrivial idempotent and $\D$ be a multiplicative Lie-type derivation from $\R$ into itself. Under certain assumptions on $\R$, we prove that $\D$ is almost additive. Let $p_n(x_1, x_2, \cdots, x_n)$ be t

Let R be a unital alternative ring with nontrivial idempotent and D:R→R be a Jordan derivation. Then D is of the form d+δ, where d is a derivation of R and δ is a singular Jordan derivatio...
