If lemmas are in service to some larger more important theorem, what is the larger more important theorem the Borel Cantelli lemmas are in service of? They seem like standalone theorem-like things to me and it makes me confused about what should be a lemma vs a theorem.

Retaliate. Prove their technical lemmas, see who's laughing then

#DARPA just announced a forthcoming program entitled "Exponentiating Mathematics", focusing on challenges to auto-formalization (and auto-decomposition of large proofs into small lemmas). The preliminary announcement (still short on many details) can be found at sam.gov/opp/4def3c13...

Trying to find the original papers from the 1900s to find what they were “lemmas” for lol

"why those two" they have, if i squint at 'em, the right shape to point a verifier at and just grind out lemmas. the other three less so, and hodge the most so

A student asked in analysis class last week what is the difference between lemmas, propositions, and theorems. Best answer I could give was “vibes.”

You can figure so much stuff out using Borel Cantelli lemmas it’s insane.
A random walker starting at position 0 will return to position 0 infinitely often in dimensions 1 and 2, but not in dimensions higher than 2.

dream is to write a 700pp doorstop called like "a leisurely stroll through projection theory" just a hideous swamp of lemmas and no examples...

note to self, lemmas:
1) seeding the prng is fine, but we can't seed the prng because that's not how google did it
2) watermarking is always noise injection
3) noise injection always causes a problem in some cases, nonlinearly dependent on how much noise
4) you can never know what those cases are

you were a marvelous proof who got stuck inside the margins and had to crawl through pages of lemmas and penumbral ink-smudges to escape

But in any case he was talking about proving theorems and lemmas (the advice specifically was you can go back and prove the lemmas you actually need) whereas the classmate thought homework

microblog sociology. theories? speculation? lemmas??
this lead me to ask on twitter: what makes the norvid cluster flourish?
in some ways there is more flourishing on bsky than twitter right now. eg the whole mini-sites. what made the old twitter flourish?

Now I can show this to my kids when I randomly let one of them choose the car song. These lemmas should satisfy them.
Random Priority—a popular no-transfer allocation mechanism—is efficient, fair, & simple to participate in. Is it the only mechanism with these properties? Marek Pycia @econ.uzh.ch and Peter Troyan, UVA Economics, answer this long-standing question in the positive.

Somebody should make a tool that takes a mathematical paper and autogenerates a "lemma flowchart" that depicts which lemmas etc. are direct inputs to which other results.
