Descrição: New aspects of exact reduced dynamics of a simple model of an open system (spin- 1 2 in a magnetic field and coupled to a Bose reservoir) are presented. A relaxation problem, final states of the system, Schrödinger-like and Heisenberg-like representations of dynamics are considered. A master equation for a statistical operator of the system and its solution are obtained, and the related question of the construction of a semigroup for the time evolution is discussed.
