| Jul 9, 2014 at 17:53 | comment | added | Khalid Bou-Rabee | Also, check out this very nice paper of Agol, Groves, and Manning: arxiv.org/pdf/1405.0726.pdf . He discusses general graph of groups in Section 3. | |
| Jul 9, 2014 at 17:50 | comment | added | user75691 | Thanks a lot again for your answer. I will see again this paper in more detail. | |
| Jul 9, 2014 at 17:42 | comment | added | Khalid Bou-Rabee | Ok :) A remark: the canonical completion works in the context of virtually special groups and it is not hard to see that free products of virtually special groups are virtually special. | |
| Jul 9, 2014 at 17:25 | comment | added | user75691 | Thanks a lot for your answer. Yes I understand that it is not possible to expect that the algebraic property can be generalised so much, but this is that I am actually asking is some notion of 'covering' using some space that involves the graph of groups decomposition of a free product(or the Bass-Serre tree) and somehow related to finite index subgroups. I am not sure of course, if this possible. | |
