Mappings preserving sum of triple products on $*$ -algebras

João Carlos da Motta Ferreira, Maria das Graças Bruno Marietto

Let $A$ and $B$ be two unital complex $*$ -algebras such that $A$ has a nontrivial projection. In this paper, we study the structure of bijective m…

Nonlinear maps preserving sums of triple products on $*$ -algebras

João Carlos da Motta Ferreira, Maria das Graças Bruno Marietto

Let $A$ and $B$ be two unital complex $*$ -algebras such that $A$ has a nontrivial projection. In this paper, we study the structure of bijective n…

Mappings preserving product $ab \pm b a^{}$ on alternative $W^{}$ -factors

João Carlos da Motta Ferreira, Maria das Graças Bruno Marietto

Let $A$ and $B$ be two alternative $W^{*}$ -factors. In this paper, we proved that a bijective mapping $Φ : A \to B$ satisfies $Φ(ab+ba^…

Filled Julia and Mandelbrot Sets for Dynamics over the Normed Real Nonassociative Algebras

João Carlos da Motta Ferreira, Maria das Graças Bruno Marietto

In this paper we introduce the notion of dynamical systems over the class of the normed real nonassociative algebras not necessarily finite-dimensional, generalize the classical fi…
