From elliptic islands to hyperbolic waves: Celebrating Pedro Duarte's 60th birthday

PUC-Rio and UFRJ, Brazil | -

We are organizing an international conference on Dynamical Systems (29 and 30 of August 2022, PUC-Rio) and a special edition of the EDAÍ seminar (2 of September 2022, UFRJ), to celebrate Pedro Duarte's 60th birthday by focusing on his research interests. This event will take place in Rio de Janeiro, Brazil.

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 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.
