TIME AT WORK (Official poster)
A trimester at Institut Henri Poincaré , Centre Emile Borel (April 18 - July 13, 2005)

The etymology of the word "ergodic'' involves the Greek word for "work.''
Ergodic theory can be viewed as the analysis of the "work'' of time.

V. Baladi (CNRS, Jussieu), J. Bricmont (Louvain-la-Neuve), P. Collet (CNRS, Ecole Polytechnique),
F. Ledrappier (University of Notre Dame), and C. Liverani (Roma II)
