| Nov 17, 2020 at 19:55 | comment | added | LSpice | @NoahSchweber, I agree that "what are the pedagogical advantages and disadvantages of this approach?" is a more reasonable question (although still, to me, suspect—one can ask the same question about any approach, whether or not it is valuable, and surely it is on the asker to demonstrate at least some reason why this particular approach deserves particular attention). | |

| Nov 17, 2020 at 19:34 | comment | added | Noah Schweber | @LSpice I somewhat disagree. While I haven't upvoted (I'm not wild about this question in its current form, and I don't know enough about the subject to say whether it's actually promising - that said, I haven't downvoted either), I think that questions about the pedagogical value of observations like these are at least sometimes good fits for MO (again, I don't have the background to say anything about this one in particular though). Tentatively I'd say that this could be a fine MO question if posed more appropriately. | |
| Nov 17, 2020 at 19:23 | comment | added | LSpice | Although phrased as a question, this seems more like a push for a certain pedagogical approach. It is surely easy to see this approach to root systems used—use it! Make your work available on your webpage or the arXiv, and solicit feedback if you like or just let it exist for whom it is useful. As for MO, what is the point? The answer to this question is "yes" or "no", and neither one of those answers seems like it will materially advance mathematical research. | |
| Nov 17, 2020 at 19:09 | comment | added | Andrei Smolensky | Could you please locate the specific place in the book by Elhamdadi and Nelson where root systems are treated as quandes? | |

| Nov 17, 2020 at 18:20 | comment | added | darij grinberg | IMHO this has the potential to be a good question, once a bit more meat is added. For instance: Are there any nontrivial properties of root systems that follow from general properties of quandles? | |
| Nov 17, 2020 at 18:01 | comment | added | Ben McKay | Serre's Complex Semisimple Lie groups has a nice definition, which I can remember. | |
| Nov 17, 2020 at 17:59 | comment | added | Noah Schweber | I think the first paragraph of this question should be cut (it's more of a personal anecdote than an actual part of a question). | |
