The necessity for a time local dimension in systems with time-varying attractors Academic Article uri icon


  • Abstract We show that a simple non-linear system for ordinary differential equations may possess a time-varying attractor dimension. This indicates that it is infeasible to characterize EEG and MEG time series with a single time global dimension. We suggest another measure for the description of non-stationary attractors.
