| Mar 2, 2012 at 17:01 | comment | added | Ronnie Brown | I'd be grateful for a reference to the work of Puig. There is an Exercise 8 on p. 379 of "Topology and groupoids" in which I suggested a kind of research project on dealing with a subalgebra, in fact an ideal, by related methods, but I am not sure if that is the good direction! | |
| Feb 20, 2012 at 17:02 | comment | added | Erwan Biland | Thank you for this answer. It turns out that I might have to work with a notion of covering morphism of G-algebras, due to Puig. I do not know if the two notions are related. Anyway, your post gave me the opportunity to learn about groupoids. Thanks ! | |
