Finite time blowup for an averaged three-dimensional Navier-Stokes equation (2014)

@dang please can we add a [2014] to the title ?

This is essentially irrelevant to the content of the post, but it's amusing to me that he casually mentions submitting to JAMS as if its acceptance were a mere formality.

This is going around due to rumors and baseless speculation on Twitter [1] right now that Anthropic has solved the Millennium problem related to Navier-Stokes [2] [1] https://x.com/AndrewCurran_/status/2096062392442724805 for example [2] https://en.wikipedia.org/wiki/Navier%E2%80%93Stokes_existenc...

Interesting to see that they are not using the coordinate-free representation (exterior calculus, differential forms) that mathematical physicists prefer to use today.

immmmmm

It’s pretty crazy what dynamics you get from NS.. until one realise they emerge from a tiny part of the solution space of Einstein equations.. which themselves emerge at the low energy limit of sth much bigger.
