Quantum Dynamical Systems with Quasi-Discrete Spectrum

ABSTRACT: We study totally ergodic quantum dynamical systems with
quasi-discrete spectrum. We investigate the classification problem
for such systems in terms of algebraic invariants. The results are
noncommutative analogs of the theory of Abramov.
