| Apr 28, 2023 at 15:58 | comment | added | Mare | @rschwieb At the beginning I wrote that we only look at finite semigroups. | |
| Apr 28, 2023 at 15:56 | comment | added | rschwieb | Sorry yeah, I missed that you wrote something similar. However, I am not aware of the version you wrote. Did someone improve the converse? The classical result I cited requires $G$ to be locally finite. | |
| Apr 28, 2023 at 15:50 | comment | added | Mare | @rschwieb Yes, I even cited that in my question. | |
