ITT /sci/ solves a Millennium Prize Problem.

How about... oh, I dunno... the Riemann Hypothesis?

https://en.wikipedia.org/wiki/Riemann_hypothesis
>the Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and the complex numbers with real part 1/2.

So all we have to do is find the zeroes of this function. How hard could that be? Finding a counterexample would be even easier, actually, and we'd fuck up a huge part of mathematics in the process!

If some random Russian dude could figure out the Poincare conjecture, then all of our brains put together here would make the Riemann hypothesis look like child's play. Let's make history, /sci/!

Everything can be solved by IUT, we should use it.

Just write something stupid on 4chan. All the zeroes will come to you and expose themselves willingly!

I really doubt youll ever fin a zero elsewhere

Lets focus on figuring out a proof

Nah, it would be easier to just find a zero that invalidates the hypothesis.

Just one little counterexample disproves it immediately. Much easier than trying to figure out an entire goddamn proof.

That would only be easier if the conjecture was false, if it was true then you can spend millennia trying to find one and come out plum handed.

Li's criterion says that proving [math]\lambda_n > 0[/math] for all [math] n \in \mathbb{N} [/math] is equivalent to proving the Riemann hypothesis.

>use real induction and prove that f(a) is nonzero and divergent on the set (0,1) \ {1/2}
>you have just proven the riemann hypothesis

[math] \displaystyle \prod_{-\infty}^{\infty}\zeta(a+xi)^{dx} = \exp(\int_{\mathbb{R}}\ln(\zeta(a+xi))dx [/math]
[math] \displaystyle \zeta(x) = \prod_{p\text{ prime}} \frac{1}{1-p^{-x}} [/math]
[math] \displaystyle \ln(\prod_{p\text{ prime}} \frac{1}{1-p^{-x}}) = \sum_{p \text{ prime}}\ln(\frac{1}{1-p^{-x}}) [/math]
[math] \displaystyle \sum_{p \text{ prime}}\ln(\frac{1}{1-p^{-x}}) = \sum_{p \text{ prime}}(\ln(1)-\ln(1-p^{-x})) = -\sum_{p \text{ prime}}\ln(1-p^{-x})[/math]
[math] \displaystyle \exp(\int_{\mathbb{R}}\ln(\zeta(a+xi))dx = \exp(-\sum_{p \text{ prime}}\int_{\mathbb{R}}\ln(1-p^{-a-xi)})dx)[/math]
[math] \displaystyle \exp(-\sum_{p \text{ prime}}\int_{\mathbb{R}}\ln(1-p^{-a-xi)})dx) = \prod_{p \text{ prime}}\exp(-\int_{\mathbb{R}}\ln(1-p^{-a-xi)})dx) [/math]

it gets messier

[math] \displaystyle \int_{\mathbb{R}}\ln(1-p^{-a-xi)})dx = \frac{i\text{Li}_2(p^{a+bi})}{\ln(p)}+b\ln(1-p^{-a-bi})-b\ln(1-p^{a+bi})+\frac{1}{2}ib^2\ln(p)+C [/math]

Although I have not examined its mathematical content, I wish you to know that I saw your [math] \LaTeX [/math] and found it unusually beatiful, at a glance.

Two issues which immediately pop out are the exponential "dx" in the beginning, and small parentheses throughout, which do not match the large operators.

Your post brings to mind two things:

1) What /is/ THE Riemann Zeta function, over the complexes, once all the brouhaha has been accounted for? A single, singular formula, which isn't just the early real motivation. This is something I've never actually checked.

2) Waht is the "Li" function? I can readily search this but I'm inviting you to add context, is the point.
>>
>>8279393
you messed up your latex pretty bad
you forgot a parenthesis on line 5 and changed an x to a b on the last line
also, i'm hoping you just copy/pasted that integral over R, because that's a definite integral with a constnat of integration
>>
>>8279422
[math] Li [/math] is usually the logarithmic integral function.

Here's a few more hours worth of work on it:
https://files.catbox.moe/ri9i0v.pdf
Prove the [math]\lambda_n[/math] sequence is monotonically increasing, and by reference to the fact that [math]\lambda_1 > 0[/math], the result follows by ordinary induction.
>>
Bump :^)
>>
>>8282390
Instead of just mindlessly bumping, how about you help?

If we can determine some sort of closed-form answer for the incomplete Bell polynomial at the bottom, the we can remove the last derivative operator. Then we just take [math] \lim_{z \to 1} \lambda_n [/math] and we'll have a simple genral form for the terms in the series, which should make it much easier to analyze, seeing as doing the same for the pre-proceesed cases of [math]n = 1[/math] and [math]n = 2[/math] appear to result in a series expressed in terms of the various Stieltjes gammas.

>>8281121
You do know that proofs usually have words in them right ? At least explain what you're doing if you are expecting anyone to even glance at it
>>
>>8283186
It's just scratch work, f a m. Though I agree his work would be more intelligible if he explained in words.
>>
>>8283198
Still, he could at least explain why he is making these computations and why he thinks they are relevant. He seems to expect people to help. The least one can expect is to know what is happening. It's like asking someone to read disgusting, non-commented code
>>
>>8283214
I explained why they're relevant in >>8281121 and >>8282423 and what I'm doing is attempting to put it into a form for which a growth rate can be determined.
