The interplay between ergodic theory and von Neumann algebra theory goes back to the examples of non-type I factors which Murray and von Neumann obtained by the group measure construction. A natural and probably definitive point of view which joins both theories has recently been exposed by P. Hahn. It uses the notion of measure groupoid, introduced by G. Mackey "to bring to light and exploit certain apparently far reaching analogies between group theory and ergodic theory".
