thx for the update.
This appears to be the most comprehensible invitation today, but of course I still understand shit.
I'm not a fan of elliptic curves, but I see myself learning about stacks in the future. Does anybody here have some more intuition about them?

To me, yes, as the vocabulary refers to more common core objects an triggers some associations.

<span class="math">\zeta(s) = 2^s\pi^{s-1}\ \sin\left(\frac{\pi s}{2}\right)\ \Gamma(1-s)\ \zeta(1-s)[/spoiler] ?

Well in any case, regarding the paper, for starters: Does somebody know how to understand his <span class="math">a\in a[/spoiler]?
I've read before that it's called "inter-universal" Teichmüller theory because he doesn't fix an underlying set universe for his study, but moved between them.
On Math overflow I read that all of this relates to non-wellfounded set theories
http://en.wikipedia.org/wiki/Non-well-founded_set_theory
and so "a in a" shouldn't scare one.

Thoughts: I'm thinking of topoi of sheaves, C^X, over a topological space X. Those are like set universes, and (geometric) morphisms (functors between topoi) are induced by continuous transformations Y->X Grothendiecks 6, etc.. Also, Mr. Samurais theories work is related to his anabelian stuff.
I've no idea if this might be how switching between universes should be interpreted, but that's also my association and I was triggered by reading about stack in it, which I guess are nicer sheaves.

"Inter-universal Teichmuller theory."

Okay, what math do I need to know in order to comprehend this? All I know right now is abstract algebra and basic topology and differential geometry.

I'm not even talking about the concepts he's trying to explain....just the wording on that first page alone where he's talking about N h = h => h = 0 is so atrocious that I had to read it three times over. And wtf is up with all the random underlining.

Algebraic geometry will be the main ingredient.
Then p-adic analysis complex differential geometry, number theory and some set theory...

>>7105456
Yeah it sucks that it's so hard to read.
Okay, so let's get thought it and try to understand what the objects are at least.

First on page 2, the second point of the first example, there are some suggestions:
he gives the example of a number h being a part of number C.
His h fits into his C because the there is an N>=2 so that h·N is something just as big or even smaller than N.
I.e. h·N<=C.
Now he say C=0 means h=0 in arithmetic, but he suggest to us to take a defining equation in this case
N·h=h. This leads to the same result, but expresses h is part of h itself.
I guess in his inter-universal world the relation is allowed and so we get new nicer spaces.

Then on the same page he gets into algebraic geometry. Fix a prime number l.
He says we consider an elliptic curve E, i.e. basically a solution space (with emphasis on space), and says for his object of interest there is a short exact sequence
0 --> mu --> E --> Z/lZ --> 0
So, stretching concepts a bit, the space E is more or less the Cartesian product of the simple arithmetic object Z/lZ and the "multiplicative subspace".
He then goes on to state the problem: For the spaces he'd need to solve his elliptic curve stuff, that relation doesn't hold.
Given what he said so far, I conclude he came up with the inter-universal theory to enable just that, introduce new nice spaces so he have split the E's apart.

Then there is q-parameter I don't know. He says q to the power of l is the other q.
Well, I don't know anything about it, but I heard the word "Frobenioid" in another thread
http://en.wikipedia.org/wiki/Frobenioid
and without knowing much about modular arithmetic, I know there are those maps
http://en.wikipedia.org/wiki/Frobenius_endomorphism
which are about mapping inside Z_p to the prime power p.

You don't get to analytically continue 0! to infinity. It's already rigorously defined as 1; it would be like saying the analytic continuation of sin(x) at 0 is 5- it just makes no sense.

>> No.7105612

it's the continuation from infinity, not to infinity, and not to the function 1 or 0, but of a function to the value 0.

I'm no algebraist or chink, but it seems what he's saying is this:

Proof of Goldbach conjecture comes down to proving that Spziro inequality.

this tautological solution, I don't really understand, but the gist of it seems to be if you think of an automorphism as instead of going between the *same* group/ring/field, as being between distinct copies of that group/ring/field in different "universes" where group/ring/field theory operates differently, then you can prove the Spziro inequality.

Inter-Universal Teichmuller theory is about doing these transformations *between* these universes.

Like I say, I'm not an expert in the field, just a keen physicist; but I've been trying to decipher some thread of that paper.

I agree with most people here that it's written like the lecture notes of a cokehead with ADHD. All those abbreviations all over the place, yet he defines the Jacobi identity twice? Could've been a bit more considerately redrafted.

Thanks for the response.

Yeah I also noticed the double Jacobi statement.

The transition of structure via automorphism seems cool.
Why would the proof by tautological, then?
Also, do you know if my idea about the universe translation as induced by the automorphism correpsonds to some sort of induced functor?

You guys claim you want to know about it, but you don't really want to invest anything.
If you really care, learn about schemes and then, in some months, come back and report about what you learned and teach others.
It's just math, if you work with it for some time, you'll understand it - also, it gives new ideas. Especially if you're into a mathematical subject like physics, knowing more math can never be bad. Witten is hailed a genius of this day, and a part of why he was so successful in his respective community is because he kept up with algebraic topology.
You don't have to understand Narutos theory - it's know to be hard. But don't say you want to know about it and not even learn the available basics of the tangible subject that motivates his work.
