Formalisation as a concrete manifestation of mathematical understanding
By formalising mathematics, not only we understand it better but we produce scientific output whose content is precisely this understanding. I will organise this argument by relating what brought m…

This. Filippo, in an ode to the mathlib community and the formalisation community in general (not just in Lean), also address the paradoxical pressures against understanding in the pursuit of prestige, i.e. the mathematical publishing industry.

But to reiterate, this is huge! It’s a really strong method of quality assurance. I have yet more faith in the encryption protocol now. But we should continue hunting for bugs in it and in the auto-formalisation.

Yet artefacts like that exact paper are pointed to triumphantly by "AI" boosters to say that their critics should be hedging. It is to be engaged with on their terms: if the Lean compiles and the formalisation matches the description, then the system must understand the proof.

Mais j’aime bcp cette formalisation ! Je n’aime pas tant le spontané, je préfère la réflexion et les jolies tournures de phrases, mais c’est bien plus difficile à faire. 🥲
J’apprécie les threads mais c’est le pb, oui. De toute façon, je les reposte tous sur Seriebox ou Livraddict.

lean-checked is the bit that catches my eye. i wonder how much human time went into the formalisation, that’s the cost i'd want to understand before getting too carried away

Merci pour le replay. Une piste qui revient souvent chez les mathématiciens : coupler les modèles de langage à un assistant de preuve comme Lean, pour que chaque étape soit vérifiée par la machine plutôt que crue sur parole. L'exposé aborde-t-il la formalisation ?

Runtime Extensions for BMSSP
A Ramos et al
We extend the AFP formalisation of the bounded multi-source shortest path algorithm of Duan et al. The extension adds a charged direct-insert relation that records both the range charged by the recurrence and the output returned by each recursive child.

In the proofs detail is everything. Formalisation would be ideal, but not attainable with current funding levels without everything grinding to halt. Or in third world shitholes, that I suffer, being forced to teach full time not having a constant stream of publications to buy the research hours.

She discusses whether the reliance on experts, the sprawling literature, and the necessary knowledge how, might be lost over time. One might thing that this new formalisation sets the proof in stone, but of course the formalisation itself doesn't help one to understand it, so doesn't help this worry

Well, the formalisation reveals that the proof was repairable only with a pretty major correction, and lots of local fixes. At the same time, the overall structure of the huge proof mostly stood strong, which speaks to the overall reliability of human mathematics.
