Description
We apply the effective approach to evaluating
semiclassical
relational dynamics to the closed Friedman--Robertson--
Walker cosmological
model filled with minimally coupled massive scalar field.
This model is interesting for studying relational dynamics
in
more general setting because (i) it features non--trivial
coupling of relational clock to evolving degrees of
freedom,
(ii) no temporally global clock variable exists, (iii) it is
non--integrable which is typical for generic dynamical
systems.
