Linear maps between C-algebras that are -homomorphisms at a fixed point

María J. Burgos, J. Cabello-Sánchez, Antonio M. Peralta

Let $A$ and $B$ be C $^{*}$ -algebras. A linear map $T : A \to B$ is said to be a $^{*}$ -homomorphism at an element $z \in A$ if $a b^{*} = z$ in $A$ implies $T (a b^{*}) = T (a) T (b)^{*} = T (z)$ , an…

A Kowalski-Słodkowski theorem for 2-local $^{*}$ -homomorphisms on von Neumann algebras

María Burgos, Francisco J. Fernández-Polo, Jorge J. Garcés +1

It is established that every (not necessarily linear) 2-local $^{*}$ -homomorphism from a von Neumann algebra into a C $^{*}$ -algebra is linear and a $^{*}$ -homomorphism. In the setting of…
