From elliptic islands to hyperbolic waves

Celebrating Pedro Duarte's 60th birthday

PUC-Rio / UFRJ, Rio de Janeiro - Brasil

This event, consisting of an international conference on Dynamical Systems and a special edition of the EDAÍ seminar, celebrates Pedro Duarte's 60th birthday by focusing on his research interests.

The main topics covered in this meeting are: the standard map with its challenges, including the existence of elliptic islands; isospectral reduction theory and stationary measures on infinite graphs; hyperbolic billiards; statistical properties of linear cocycles presenting hyperbolic waves, as well as positivity and continuity of their Lyapunov exponents; the study of ergodic Schrödinger operators in mathematical physics.

The (spectral) gap between the two-day conference at the beginning of the week and the one-day EDAÍ seminar (a traditional carioca event in dynamics) at the end of the week, will allow speakers and participants to collaborate with local researchers.


  • The conference: 29 and 30 August 2022, from 10:00 to 18:00
  • The EDAÍ seminar: 02 September 2022, from 10:00 to 18:00


  • In order to help the organizers with the practicalities of the event, all participants have to register in advance.
