Bilocal *-automorphisms of B(H) satisfying the 3-local property

Ahlem Ben Ali Essaleh, Mohsen Niazi, Antonio M. Peralta

We prove that, for a complex Hilbert space $H$ with dimension bigger or equal than three, every linear mapping $T : B (H) \to B (H)$ satisfying the 3-local property is a $^{*}$ -monomorph…

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…
