| Jul 10, 2016 at 13:59 | comment | added | T. Amdeberhan | @FedorPetrov: very nice argument, thanks. Will see how to adopt this to the case (2), e replaced by t, or someone else does. I'm also curious if there is any other approach. | |
| Jul 8, 2016 at 13:26 | comment | added | Francesco Polizzi | @FedorPetrov: well, the way in which the question is asked (for instance, the imperative tone and the last remark) gives the impression that it is a challenge for the MO users, and this kind of questions are surely non-acceptable here. Rewording the question in the sense you suggest might be a possibility. | |
| Jul 8, 2016 at 13:20 | comment | added | Fedor Petrov | @FrancescoPolizzi sorry, this text was written before the question became officially considered an off-topic, or simultaneously. If you find it reasonable, I may remove it and send to OP elsewhere (I know him personally). I think, if the question is supposed to mean something like 'please explain this fact arising in my research with a short and elegant argument', it is suitable on MO, there are many such questions. | |
| Jul 8, 2016 at 13:09 | comment | added | Francesco Polizzi | As a rule of thumb, one should not answer off-topic questions (for instance, in order not to encourage them). | |
