Godofredo Iommi (PUC), Upper semi-continuity of the entropy map for Markov shifts

Abstract: In this talk I will show that for finite entropy countable Markov shifts the entropy map is upper semi-continuous when restricted to the set of ergodic measures. This is joint work with Mike Todd and Anibal Velozo.
