Terence Tao and the Lean community are currently formalizing his et al.'s proof of the Polynomial Freiman Rusza cojecture.

This market resolves when the Polynomial Freiman-Rusza is formalized, according to either the final goal on this page being green, or consensus on Zulip being that the project is complete.

New dates to be added at my discretion. Past dates to be resolved immediately.

"The #Lean4 project to formalize the proof of the Polynomial Freiman-Ruzsa conjecture has succeeded after three weeks, with the dependency graph completely covered in a lovely shade of green: https://teorth.github.io/pfr/blueprint/dep_graph_document.html , and the Lean compiler reporting that the conjecture follows from standard axioms."

@kiudee Yep, Tao posted on Zulip saying it was complete as well, and as no one seems to disagree, that makes this resolve now. Thanks everyone!

`lem-bsg` is claimed by Yaël and Bhavik per https://leanprover.zulipchat.com/#narrow/stream/412902-Polynomial-Freiman-Ruzsa-conjecture/topic/Outstanding.20tasks.2C.20version.204.2E0 ; term finishes on 1st Dec (https://www.cam.ac.uk/about-the-university/term-dates-and-calendars) and my bet is that Yaël won't be able to resist cracking on with it as soon as term ends ;) Paul Lezeau is an unknown quantity to me, but the PR for the distance increment bound is https://github.com/teorth/pfr/pull/108 .

So shouldn't the later dates be higher than the more recent dates?

@asmith Yeah oops - later dates are guaranteed to resolve YES if earlier ones do, thanks for catching that. Feel free to correct it yourself.

Note to self and others: When Kevin publishes a blueprint for his FLT project, we should make a big multi-market on all the subgoals he puts in.
