BERGER AND TURAEV'S PROOF OF HERMAN'S CONJECTURE OF POSITIVE ENTROPY

LA DÉMONSTRATION DE LA CONJECTURE DE L’ENTROPIE POSITIVE D’HERMAN D'APRES BERGER ET TURAEV

Abstract

We present the proof of Berger and Turaev of Herman's positive entropy conjecture. In every neighbourhood of identity in the set of smooth symplectic diffeomorphisms of the 2-dimensional disc, there exists a diffeomorphism with positive metric entropy.
