Estimating covariant Lyapunov vectors from data
Christoph Martin, Nahal Sharafi, Sarah Hallerberg
Covariant Lyapunov vectors characterize the directions along which perturbations in dynamical systems grow. They have also been studied as predictors of critical transitions and ex…
Predictability of Critical Transitions
Xiaozhu Zhang, Christian Kuehn, Sarah Hallerberg
Critical transitions in multistable systems have been discussed as models for a variety of phenomena ranging from the extinctions of species to socio-economic changes and climate t…
When are Extreme Events the better predictable, the larger they are?
S. Hallerberg, H. Kantz
We investigate the predictability of extreme events in time series. The focus of this work is to understand under which circumstances large events are better predictable than small…
Precursors of extreme increments
Sarah Hallerberg, Eduardo G. Altmann, Detlef Holstein +1
We investigate precursors and predictability of extreme increments in a time series. The events we are focusing on consist in large increments within successive time steps. We are…
Reactions to extreme events: moving threshold model
Eduardo G. Altmann, Sarah Hallerberg, Holger Kantz
In spite of precautions to avoid the harmful effects of extreme events, we experience recurrently phenomena that overcome the preventive barriers. These barriers usually increase d…
