Phase space representation

  Deterministic dynamical systems describe the time evolution of a system in some phase space tex2html_wrap_inline6541. They can be expressed for example by ordinary differential equations
 equation4408
or in discrete time tex2html_wrap_inline6543 by maps of the form
 equation4413
A time series can then be thought of as a sequence of observations tex2html_wrap_inline6545 performed with some measurement function tex2html_wrap_inline6547. Since the (usually scalar) sequence tex2html_wrap_inline6549 in itself does not properly represent the (multidimensional) phase space of the dynamical system, one has to employ some technique to unfold the multidimensional structure using the available data.
