Brown-Voiculescu entropy revisited
Bhishan Jacelon, Robert Neagu
Aided by the tools and outlook provided by modern classification theory, we take a new look at the Brown-Voiculescu entropy of endomorphisms of nuclear C*-algebras. In particular,…
An Elliott intertwining approach to classifying actions of C-tensor categories
Sergio Girón Pacheco, Robert Neagu
We introduce a categorical approach to classifying actions of C-tensor categories on C-algebras up to cocycle conjugacy. We show that, in this category, induc…
The stable uniqueness theorem for unitary tensor category equivariant KK-theory
Sergio Girón Pacheco, Kan Kitamura, Robert Neagu
We introduce the Cuntz-Thomsen picture of -equivariant Kasparov theory, denoted , for a unitary tensor category with countably m…
On a Rokhlin property for abelian group actions on C-algebras
Johannes Christensen, Robert Neagu, Gábor Szabó
In this article, we study the so-called abelian Rokhlin property for actions of locally compact, abelian groups on C-algebras. We propose a unifying framework for obtaining var…
Inclusions of real rank zero
James Gabe, Robert Neagu
We introduce a notion of real rank zero for inclusions of C-algebras. After showing that our definition has many equivalent characterisations, we offer a complete description o…
Generic classification of the quasi-free flows on the Cuntz algebra
Robert Neagu
In this article we show that the quasi-free flows on the Cuntz algebra are generically classifiable by the inverse temperature of their unique KMS state. Along the…
