what do theorems mean in tlt? that bit always confused me

a theorem is a (mathematical?) statement that has been proven as true (using a proof) and is often used to solve more complicated problems. i.e. the Pythagorean theorem being used to solve for various properties of a right triangle, and further than that, it can be used for useful IRL stuff like architecture and getting a plane off the ground.

the Locked Tomb treats necromancy like a science, with (unexplained) rules, methods, equations, theorems, etc. Harrowhark mentions the "theorem mathematics" of the creche massacre when she confesses to John in HtN, and later on in the same book Ianthe is mentioned as having a notebook filled with "substantial mathematics" related to her necromantic study.

THEREFORE when they say "theorem" in TLT I imagine how in order to get a plane off the ground you have to do a lot of math first to calculate stuff like interia and force and air resistance and friction, and then to keep it flying you have to do yet more math and think about things like how you will lose some amount of energy as heat.

following that, in order to get a skeleton to fold your laundry you have to do a lot of math first about the energy requierments of cell division (regarding building the skeletal frame up from a single bone chip), cell differentiation (building out ligaments as needed), etc necromantic verbage, and then to KEEP it folding that laundry you have to do yet more math about like, i dunno. Gravity and energy loss.

it seems like a lot of work, honestly. no wonder normal, non-Lyctoral necromancers are always bleeding and sweating all over the place

Okay, so, the Intermediate Value Theorem (IVT) clearly states that if you start from point (a,f(a)), below the x-axis, and move towards (b,f(b)) above the x-axis without lifting your pen up, you have to cross the x-axis at some point; (x_0,0) here. But, isn't that too obvious to be a theorem?

Can you see the hidden implication here for the foundations of mathematics?

The Infinite Monkey Theorem

“The infinite monkey theorem states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type any given text, including the complete works of William Shakespeare” - Wikipedia

so could the monkeys finish writing the entire code for yandere simulator before the creator finishes it?

Louisiana students Ne’Kiya Jackson and Calcea Johnson wowed their teachers in 2022 when they discovered a new way to prove the 2000-year-old Pythagorean theorem in response to a bonus question in a high school math contest. But that was only the beginning.

A volunteer at their former school, New Orleans’ St. Mary’s Academy, encouraged them to submit their work on the famous mathematical theory to a professional conference, and in March 2023 they became the youngest people to present at the American Mathematical Society’s Southeastern Sectional conference in Atlanta. Their appearance elicited a wave of media coverage, including a spot on “60 Minutes.” The pair also received symbolic keys to the city of New Orleans and a shout-out from Michelle Obama.

Now Jackson and Johnson, who started college last year, have notched another achievement: authoring an academic paper detailing their original proof — plus nine more. Their work published Monday in the scientific journal American Mathematical Monthly.

tarski's fixed point theorem!! it's so easy to intuitively understand, and i almost use it for every fixed point problem I encounter, be it in metric spaces, topology or real analysis

Math people, reblog with your fav theorem and why.

I'll start, the Wedderburn-Artin theorem is a beautiful structure theorem on semisimple rings which says they decompose uniquely as a product of matrix rings over division rings. This is a beautiful result but it also underlies a lot of very cool theory like Brauer Theory, Galois Cohomology and the theory of Galois and Étale Algebras.

What's yours?

Ok, the above is obviously low key dystopic but at the same time I do love an informal or metaphorical theorem name, like the ham sandwich theorem (given any n regions in R^n, there exists an (n-1)-plane bisecting all three) or the shoes and socks lemma, i.e., (f ∘ g)^-1 = (g^-1) ∘ (f^-1).

You guys know the squeeze theorem, a.k.a. the sandwich theorem? The one where if you have 3 functions that satisfy:

g(x) <= f(x) <= h(x)

And the following is true (as x approaches a):

L = lim g(x) = lim h(x)

Then (as x approaches a):

lim f(x) = L

Well it just clicked for me that in my Eastern European country, we call it "the two policemen lemma". Imagine how much of a police state it must be, that people see a line squished between two other lines and think: "Damn, another enemy of the state..."
