Haar measure for measure groupoids

Author:

Hahn Peter

Abstract

It is proved that Mackey’s measure groupoids possess an analogue of Haar measure for locally compact groups; and many properties of the group Haar measure generalize. Existence of Haar measure for groupoids permits solution of a question raised by Ramsay. Ergodic groupoids with finite Haar measure are characterized.
