@pbelmans Yes, non-stable rationality would be more approachable for AI. I'd let it classify low-rank S_n lattices and disprove stable permutation with the matrix-lattice. My guess is that n=8,9 and all primes >= 11 give non-stable rational varieties.

Ok, there's a counterexample to the Jacobian conjecture https://t.co/ZVuS8Hgq9t
Next goal : counterexample to the rationality conjecture for pairs of nxn matrices under simultaneous conjugation?

[lieven le bruyn @lievenlb]

@pbelmans n=5 would be great

@chessguessr No, even afterwards the solution was incorrect. Not only did you swap sides, but you incorrectly denoted moves by takes. I've reposted the same line after two hours and then it was finally accepted.

Ditto here. You can still find me on https://t.co/bNMJGUfela and I'll move to https://t.co/kmfiWtA5tE

Exactly 90 years ago, on December 10th 1934, Weil, Delsarte, Cartan, Dieudonne, de Possel and Chevalley got together in 'A Capoulade' for the first (proto) #Bourbaki meeting.

[lieven le bruyn @lievenlb]

Exactly 10 years ago Alexander Grothendieck died, and Nicolas Bourbaki was temporarily resurrected to announce this in the French newspaper Le Monde.

Next try to put a bit of Bourbaki/Dema lore in a YouTube clip : https://t.co/FbHtERNFMu

I thought that trying to identify the shirt-photos was a wild goose chase. In this particular case, they try to say something about Vialism, or at least they relate seizing to the mystic experience of having a vision. Are there more shirts that may be interesting lore-wise?

[KEONS @KEONSEAST]

we have found every photo on tylers night 8 LA shirt!

[lieven le bruyn @lievenlb]

@KEONSEAST Perhaps it's a hint to the more famous picture 'vision of Joannes Chisius' (aka Giovanni Chigi). This one has 4 "putti", one holding a skull, one a crown, one the coat of arms of Pope Alexander VII and one... is a torchbearer. Also Pope Alexander VII's history is interesting.

[lieven le bruyn @lievenlb]

@KEONSEAST What about this portrait of the Augustinian monk Beato Giovanni Chigi?

Closed comments for now on https://t.co/R7Cpj6nhSo because someone seems to hate a certain post (or me altogether). If you have something worthwhile to share, email me, and we'll turn it into a genuine comment.

Made a clip on 'bearded man', photoshopped into a @tylerrjoseph tweet. It is based on finds by @keonseast and @nalbis. Link in the comments. Now, working on 'Nico's backstory', based on a document found in the Bourbaki archives. Hopefully will come out next week.

Here's what i know about the 'bearded man' from a 2018 tweet by @tylerrjoseph, and what i think he symbolises.

If the Bourbaki group was meant to be the Bishops, then there's no other candidate for Clancy than Alexander Grothendieck.

I agree more with George Lucas than Alfred Hitchcock in this particular case.

[lieven le bruyn @lievenlb]

Constantin Denis Bourbaki (the father of General Charles Bourbaki, of lore-reputation) was beheaded in (or after) the battle at Katamero.

[KEONS @KEONSEAST]

we have now had two cases of a head being removed from a body on Tyler's shirts
