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…

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…

On topologically zero-dimensional morphisms
Jorge Castillejos, Robert Neagu
We investigate -homomorphisms with nuclear dimension equal to zero. In the framework of classification of -homo-morphisms, we characterise such maps as those that can be ap…
