Universal C*-algebras generated by doubly non-commuting isometries

Marcel de Jeu, Alexey Kuzmin, Paulo R. Pinto

We give an explicit injective representation of the universal $C^{*}$ -algebra that is generated by doubly non-commuting isometries. This injectivity allows us to prove th…

Hermitian crossed product Banach algebras

Rachid El Harti, Paulo R. Pinto

We show that the Banach *-algebra $ℓ^{1} (G, A, I^\pm)$ , arising from a C*-dynamical system $(A, G, I^\pm)$ , is an hermitian Banach algebra if the discrete group $G$ is finite or abelian (or…
