Abstract
We derive a purely algebraic framework for the identi cation of hierarchy
equations of motion that induce completely positive dynamics and demonstrate the applicability of our approach with several examples. We nd bounds on the violation of complete positivity for microscopically derived hierarchy equations of motion and construct well-behaved phenomenological models with strongly non-Markovian revivals of quantum coherence.
