Outline of Final Research Achievements

I studied operator algebras and dynamical systems from various perspectives. In particular, I focused on classification of group actions on simple nuclear C*-algebras and analysis of minimal dynamical systems on Cantor sets. For instance, I obtained a complete classification of outer actions of poly-Z-groups on Kirchberg algebras up to cocycle conjugacy. Secondly, I classified etale groupoids arising from finite products of shifts of finite type, and computed the homology groups of the etale groupoids and the abelianizations of the associated topological full groups.
