One-parameter semigroups of orthogonality preservers of JB*-algebras

JJ Garcés, AM Peralta - Advances in Operator Theory, 2021 - Springer
In a first objective, we improve our understanding about surjective and bijective bounded
linear operators preserving orthogonality from a JB*-algebra AA into a JB*-triple E. Among …

Linear maps which are anti-derivable at zero

DA Abulhamil, FB Jamjoom, AM Peralta - Bulletin of the Malaysian …, 2020 - Springer
Abstract Let T: A → XT: A→ X be a bounded linear operator, where A is a C^* C∗-algebra,
and X denotes an essential Banach A-bimodule. We prove that the following statements are …

A linear preserver problem on maps which are triple derivable at orthogonal pairs

ABA Essaleh, AM Peralta - Revista de la Real Academia de Ciencias …, 2021 - Springer
A linear map** T on a JB∗-triple E is called triple derivable at orthogonal pairs if for every
a, b, c∈ E with a⊥ b we have 0={T (a), b, c}+{a, T (b), c}+{a, b, T (c)}. We prove that for each …

On the strict topology of the multipliers of a JB-algebra

FJ Fernández-Polo, JJ Garcés, L Li… - Revista de la Real …, 2023 - Springer
We introduce the Jordan-strict topology on the multiplier algebra of a JB∗-algebra, a notion
which was missing despite the forty years passed after the first studies on Jordan multipliers …

Conjugate Linear Maps from C-Algebras into Their Dual Spaces which are Ternary Derivable at the Unit Element

Z Khalili, MR Miri, M Niazi - Results in Mathematics, 2020 - Springer
We prove that every continuous conjugate linear map** from a unital C^*∗-algebra A into
its dual space, A^* A∗, which is ternary derivable at the unit element of A is a ternary …
