The Mazur-Ulam property for the space of complex null sequences
Antonio Jiménez-Vargas, Antonio Morales Campoy, Antonio M. Peralta +1
Given an infinite set , we prove that the space of complex null sequences satisfies the Mazur-Ulam property, that is, for each Banach space , every surjective isomet…

Weak-local derivations and homomorphisms on C*-algebras
Ahlem Ben Ali Essaleh, Antonio M. Peralta, María Isabel Ramírez
We prove that every weak-local derivation on a C-algebra is continuous, and the same conclusion remains valid for weak-local derivations on von Neumann algebras. We further…

A Kadec-Pelczyński dichotomy-type theorem for preduals of JBW*-algebras
Francisco J. FernÁndez-Polo, Antonio M. Peralta, MarÍa Isabel RamÍrez
We prove a Kadec-Pelczyński dichotomy-type theorem for bounded sequences in the predual of a JBW*-algebra, showing that for each bounded sequence in the predual of a JBW$^*…
