Zero Entropy System (1804)
Système d’entropie nulle
Dates: 27 November – 1 December 2017 at CIRM (Marseille Luminy, France)

In this small workshop, we discuss zero entropy systems, focusing on renormalization scheme, having in mind applications to number theoretical algorithms. 

Such systems are of zero entropy in additive action, but of positive entropy in renormalization structure, and form a nice pair of dynamical systems whose fundamental example is given by irrational rotations and classical continued fraction.
