Foliation groupoids and their cyclic homology
M. Crainic, I. Moerdijk
In this paper we study the Lie groupoids which appear in foliation theory. A foliation groupoid is a Lie groupoid which integrates a foliation, or, equivalently, whose anchor map i…

A Homology Theory for Etale Groupoids
Marius Crainic, Ieke Moerdijk
Etale groupoids arise naturally as models for leaf spaces of foliations, for orbifolds, and for orbit spaces of discrete group actions. In this paper we introduce a sheaf homology…
