This is an online research seminar on dynamical systems theory. It takes place every Friday (except Brazilian holidays) from 11 am to 12 am (local time in Rio de Janeiro, Brazil) using the platform zoom.

This seminar is part of an initiative to combat the current difficult situation of isolation and mathematical (not only) depression. In those times active resistance is fundamental. This is our proposal. We invite you to join us.

The seminar announcement is sent through the mailinglist DinamiCarioca (see also here).
If you are no member of "dinamicarioca" and are interested in receiving information about this seminar please send an email to moc.liamg|0202acimanidaicnetsiser#moc.liamg|0202acimanidaicnetsiser and you will be included in the mailing list of this seminar.

Upcoming seminars:

22 May | 11h00min | Davi Obata (Univ. Cergy-Pontoise, France)
Title: Uniqueness of the measure of maximal entropy for the standard map
Abstract: The standard family (or Taylor-Chirikov standard family) is an example of a family of dynamical systems having simple expressions but with complicated dynamics. A famous conjecture of Sinai is that for large parameter the standard map has positive entropy for the Lebesgue measure.
In this seminar, I will talk about the uniqueness of the measure of maximal entropy (m.m.e.) of the standard map for sufficiently large parameters. There are several other properties obtained for this m.m.e. We obtain that it is Bernoulli; the periodic points whose Lyapunov exponents are bounded away from zero equidistribute with respect to the m.m.e. We also obtain estimates of the Hausdorff dimension of the measure and of its support.
