| Feb 2, 2016 at 14:53 | comment | added | YCor | Steven, please specify if you require an action by homeomorphisms or preserving some further structure. Also, please define cocompact, whose meaning is clear if the action is proper but has several non-equivalent meanings otherwise (namely one can require, or not, that the quotient be Hausdorff). | |

| Feb 2, 2016 at 14:50 | comment | added | YCor | @IanAgol: no, left-orderable countable groups do not necessarily act freely continuously on the line. A group acting freely continuously on the line is abelian. | |
