| May 23, 2014 at 14:49 | comment | added | Johannes Hahn | @MinimusHeximus You don't have to be "familiar". That real matrix groups are topological groups w.r.t. the euclidean topology is immediately obvious. | |
| May 23, 2014 at 14:39 | comment | added | Minimus Heximus | @JohannesHahn: I didn't have an example of topologizable but Alexandrov non-topologizable. I'm not so familiar with Lie groups and matrix groups. | |
| May 23, 2014 at 14:09 | comment | added | Johannes Hahn | Since the discrete and the indiscrete topology are always compatible with the group structure, having three topologies isn't really that big of a requirement. In particular: Any (at least one-dimensional) group theoretically simple Lie-group will satisfy it. | |
