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…

Approximate factorization properties for operator systems
Roy Araiza, Larissa Kroell, Travis Russell +1
We show that many of the standard nuclearity properties considered in the literature for the hierarchy of operator system tensor products can be expressed as approximate factorizat…

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…
