| Mar 2, 2012 at 11:08 | comment | added | Victor | HW, actually so far it appeared only in my thesis. I could send you (and anybody else interested) a pdf with the thesis, just write to me to [email protected] for this. | |
| Mar 2, 2012 at 11:03 | comment | added | HJRW | Perhaps you could give a reference for this fact in the semigroup case? | |
| Mar 2, 2012 at 11:00 | comment | added | Victor | Hi Tara. It is quite strange, but for groups this question is much harder to deal with than that for semigroups. Actually we proved the semigroup statement with Nik for the purposes of seeing how hopficity is preserved by finite Rees extensions, so we found this property on the go, by accident. This property is inetersting on its own. | |

I should have checked what you wrote more thoroughly. Anyway, I deleted my answer, since it contributes nothing and so it's better for the question to still have 0 answers. | |
