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…
