| Jul 9, 2022 at 8:13 | comment | added | Bhaskar Vashishth | "topological rings under various topologies" means if we give R various topologies, whatever ring we select mainly either Z or C or Reals , how will that topology affect the group ring? | |
| Jul 8, 2022 at 13:33 | comment | added | Sergei Akbarov | And what is meant by "topological ring" of the group? | |
| Jul 8, 2022 at 11:36 | comment | added | Mithrandir | @SergeiAkbarov yes, apologies | |
| Jul 8, 2022 at 11:24 | comment | added | Sergei Akbarov | @Mithrandir do you mean $gHg^{-1}=H$? | |
| Jul 8, 2022 at 11:19 | comment | added | Mithrandir | In this context, I assume "units" refer to multiplicatively invertible ring elements. Also, give a subgroup $H$ of $G$, one can ask which units $g$ of group ring $RG$ normalize $H$; that is, satisfy $gHg^{-1}$. | |
| Jul 8, 2022 at 10:25 | comment | added | Sergei Akbarov | I think, you should explain the meaning of the terms, because this seems to be addressed to specialists in functional analysis, and at least some of them (including me) do not know what is meant by "units", "normalizer problem", etc. And the question itself should be clarifierd, in my opinion. | |
