International Conference on Dynamical Systems

Celebrating the 60th Birthday of Marcelo Viana

IMPA, Rio de Janeiro, October 24 – 28, 2022

For the last several decades, the Dynamics group at IMPA has been organizing international conferences on a roughly quadrennial basis. In this year’s edition we take the occasion to celebrate the 60th birthday of Marcelo Viana. 

Following the tradition of previous events, this will be a broad meeting, covering most active topics and attracting many of the very best researchers in the field. We expect plenty of interesting new developments to be presented at the conference.
