Prof. Syamal Kumar Dana, a Honorary Senior Research Scientist, Department of Mathematics, National Institute of Technology, Durgapur gave a talk on  Extreme events: Dynamical system and Networks on 27 December. Here is the summary of the talk as explained by Prof. S K Dana:

Examples of extremes are abundant in public views, mentioning here only few of them such as tsunamis, floods, earthquakes, pandemics, epileptic seizures, wars etc. All such extreme events have a devastating impact on life and infrastructure. Predicting extreme events is the most important task for mitigating a disaster caused by the extreme events. Modeling such complex phenomena is difficult. Available data records are either huge to handle or too small for the purpose of prediction. Fortunately, relatively simple deterministic dynamical models help understanding extreme events in laboratory experiments and theoretical studies. I will try to elaborate some of the models, single systems and networks of systems to explain how extreme events have been investigated in the last two decades vis-à-vis our studies on the phenomena, and the most generic dynamical processes of their origin that have been explored so far.
