  • Mappings preserving sum of products a ◦ b + ba* on factor von Neumann algebras 
    Ferreira, J.C.M.; Marietto, M.G.B. (Algebra and Discrete Mathematics, 2021)
    In this paper, we proved that a bijective mapping Φ : A → B satisfies Φ(a ◦ b + baΦ) = Φ(a) ◦ Φ(b) + Φ(b)Φ(a)* (where ◦ is the special Jordan product on A and B, respectively), for all elements a, b ∈ A, if and only if Φ ...
