Concept of spatial deterministic chaos (SDC) was
justified. An attempt to give a set-theoretic definition of SDC
was undertaken. In order to provide a mathematical description of
SDC the transition from ordinary differential equations (ODEs) to
discrete maps (DMs) without use of instantaneous response
approximation was justified. Developed theoretical theses were
used to derive a model of nonlinear phase shift dynamics in
nonlinear ring interferometer (NRI) in the form of DM. In case of
the model discrete realizations, phase portraits and Fourier's
spectrums illustrating peculiarities of SDC in ring interferometer
were constructed. Concept of DM undergoing an evolution was
introduced.
Key words:
spatial deterministic chaos, Lyapunov's exponents,
