A short (10 pages) survey of old and recent results of ergodists and probabilists: Barlow, Beghdadi-Sakrani, Dubins, Émery, Feldman, Heicklen, Hoffman, Knight, Le Gall, Schachermayer, Smorodinsky, Song, Stepin, Tsirelson, Vershik, Warren, Yor. Bibl. 44 refs.
Given a system whose time evolution is random, we often try to describe it as a deterministic system under independent random influences. Doing so, we reduce complicated statistical correlations to a complicated but deterministic mechanism, and a stochastic but uncorrelated noise. That is the idea of innovation. The corresponding mathematics is surprisingly interesting.
