Are chaotic systems dynamically random ?
Physical systems can be characterized by several types of complexity measures which indicate the computational resources employed. With respect to these measures, several chaos classes may be distinguished. There exists a constructive approach to random physical motion which operates with computable initial values and deterministic evolution laws. For certain limits, these chaos classes render ...
متن کاملTesting whether two chaotic one dimensional processes are dynamically identical
Consider the situation where two individuals observe the same chaotic physical process but through time series of different measured variables (e.g., one individual measures a temperature and the other measures a voltage). If the two individuals now use their data to reconstruct (e.g., via delay coordinates) a map, the maps they obtain may appear quite different. In the case where the resulting...
متن کاملEukaryotic cells are dynamically ordered or critical but not chaotic.
Two important theoretical approaches have been developed to generically characterize the relationship between the structure and function of large genetic networks: the continuous approach, based on reaction-kinetics differential equations, and the Boolean approach, based on difference equations and discrete logical rules. These two approaches do not always coincide in their predictions for the ...

متن کاملWhich Properties of a Random Sequence Are Dynamically Sensitive?
Consider a sequence of i.i.d. random variables, where each variable is refreshed (i.e., replaced by an independent variable with the same law) independently, according to a Poisson clock. At any xed time t, the resulting sequence has the same law as at time 0, but there can be exceptional random times at which certain almost sure properties of the time 0 sequence are violated. We prove that the...
