Professor Gilles Dowek (Inria, École Polytechnique, https://who.rocq.inria.fr/Gilles.Dowek/index-en.html ) will give a session, with subject

Chaos and the principle of a bounded density of information.

The session will take place on Thursday 25th April 2013 at 18.30 at the Amphitheater of the Old buildings of the Electrical and Computer Engineering School at the Zografou Campus (http://map.ntua.gr/google.htm)

Abstract: In this talk, we will compare two definitions of the notion of a chaotic transformation: sensitivity to initial conditions and sensitivity to perturbations. Only the later is compatible with the idea that information has a finite density. https://who.rocq.inria.fr/Gilles.Dowek/Publi/csr.pdf
