Characterization of minimal tripotents via annihilators and its application to the study of additive preservers of truncations

Lei Li, Siyu Liu, Antonio M. Peralta

The contributions in this note begin with a new characterization of (positive) scalar multiples of minimal tripotents in a general JB-triple , proving that a non-zero elemen…

Maps preserving the truncation of triple products on Cartan factors

Jorge J. Garcés, Lei Li, Antonio M. Peralta +1

Let and be two families of Cartan factors such that all of them have dimension at least , and consider the atomic JBW-triples $A=…

M-ideals in real operator algebras

David P. Blecher, Matthew Neal, Antonio M. Peralta +1

In a recent paper we showed that a subspace of a real JBW*-triple is an M-summand if and only if it is a weak*-closed triple ideal. As a consequence, M-ideals of real JB*-triples,…

On the equivalence of all notions of generalized derivations whose domain is a C-algebra

Amin Hosseini, Antonio M. Peralta, Shanshan Su

Let be a Banach bimodule over an associative Banach algebra , and let be a linear mapping. Three main uses of the term \e…

-ideals, yet again: the case of real JB-triples

David P. Blecher, Matthew Neal, Antonio M. Peralta +1

We prove that a subspace of a real JBW-triple is an -summand if and only if it is a weak-closed triple ideal. As a consequence, -ideals of real JB-triples corresp…
