Summary:
The eld of research in this dissertation is concerned with structural study of open/closed
quantum systems, especially regarding bipartite structures. Using entanglement relativity rule,
it is demonstrated quantum correlations relativity, as a generalization toward case of mixed
bipartite states. As a consequence of quantum correlations relativity, it turns out that so called
Nakajima-Zwanzig projection method has limitation: for alternate structure the building of
proper master equation must be started from the scratch. On the other hand, regarding the
appearance of a classical world in quantum theory", structural analysis bring to conclusion that
environment is choosing the most classical structure: classicality is a matter of the distingushed
composite system structure. Structuralistic way of thinking shows as natural in theory of
quantum scattering, seen as a fundamental way of interaction in many-particle systems. In
turn, via theory of asymptotic completeness..., then associated interpretation (of Kitada) it is
possible to set specic view of the quantum unitary dynamics, where time is classical hidden
parameter, giving rise to so called local time scheme. Analysis shows de
ection from standard
dynamics and novel insights into aspects of decoherence theory, non-markovianity od system
dynamics etc.
