C*-envelopes of tensor algebras of product systems

Camila F. Sehnem

Let $P$ be a submonoid of a group $G$ and let $E = (E_{p})_{p \in P}$ be a product system over $P$ with coefficient C*-algebra $A$ . We show that the following C*-alg…

Equilibrium on Toeplitz extensions of higher dimensional noncommutative tori

Zahra Afsar, Marcelo Laca, Jacqui Ramagge +1

The C*-algebra generated by the left-regular representation of $N^{n}$ twisted by a $2$ -cocycle is a Toeplitz extension of an $n$ -dimensional noncommutative torus, on which…

Toeplitz algebras of semigroups

Marcelo Laca, Camila F. Sehnem

To each monoid $P$ that embeds in a group we associate a universal Toeplitz C*-algebra $T_{u} (P)$ defined via generators and relations; $T_{u} (P)$ is a quotient of Li's semigroup C*-al…
