Injective envelopes of partial C*-dynamical systems

Matthew Kennedy, Larissa Kroell, Camila F. Sehnem

We extend Hamana's theory of injective envelopes, along with several key features of the theory, to the realm of partial C*-dynamical systems. In particular, we show that a partial…

Primality and the ideal intersection property for reduced crossed products

Matthew Kennedy, Larissa Kroell, Camila F. Sehnem

We consider the ideal structure of reduced crossed products over discrete groups. First, we completely characterize primality for reduced crossed products. Second, we characterize…

On Toeplitz algebras of product systems

Elias G. Katsoulis, Marcelo Laca, Camila F. Sehnem

In the setting of product systems over group-embeddable monoids, we consider nuclearity of the associated Toeplitz C*-algebra in relation to nuclearity of the coefficient algebra.…

Equivalence of definitions of AF groupoid

Lisa Orloff Clark, Astrid an Huef, Rafael P. Lima +1

We prove the equivalence of two definitions of AF groupoid in the literature: one by Renault and the other by Farsi, Kumjian, Pask and Sims. In both definitions, an AF groupoid is…

C*-envelopes of tensor algebras of product systems

Camila F. Sehnem

Let be a submonoid of a group and let be a product system over with coefficient C*-algebra . 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 twisted by a -cocycle is a Toeplitz extension of an -dimensional noncommutative torus, on which…
