Random walks on groups and random transformations. (English) Zbl 1053.60045
Hasselblatt, B. (ed.) et al., Handbook of dynamical systems. Volume 1A. Amsterdam: North-Holland (ISBN 0-444-82669-6/hbk). 931-1014 (2002).
This paper, which is a chapter in a contributed book, deals with three topics: random walks on matrix groups (first section), random walks on general (locally or discrete) groups (second section), and random walks on groups of transformation of measure spaces and manifolds (third section). Section 1 is mainly concerned with laws of large numbers with random matrices and the techniques so involved are, among others, Markov processes, algebraic group and unitary representation. Section 2 focuses on the connections between the properties of the group and the behaviour of the random walks defined on it. Section 2 goes from the random ergodic theorem to the random-walk-based notion of entropy, in the framework of diffeomrphisms of manifolds.
