The main objectives of this meeeting are to exchange ideas and to explain techniques used in the study of Lyapunov exponents.

Each speaker is invited to define a concept, to describe a proof technique and to illustrate it in a simple yet relevant context, in other words, to reveal some of the secrets of her or his trade.

“Lyapunov exponents of probability distributions with non-compact support”

Tendas de Artes   PUC-Rio

The workshop takes place in one of the two (adjacent) tents of the Department of Arts and Design.

The tents are on the other side of the river (Rio Rainha) from the Mathematics Department, close to the campus church (Igreja Sagrado Coração de Jesus) and to the museum (O Solar Grandjean de Montigny), but they are somewhat hidden; click here to see a map of the campus.
