 2020-09-12, 19:39 #1 jrsousa2   Dec 2018 Miami 29 Posts The prime counting function conjecture Don't swallow me alive for this, but I was wondering if somebody can be kind enough to test this conjecture with a large enough say $x>50$ using a powerful computer: $\pi(x) \sim -16\sum _{h=1}^{\infty}\frac{x^{2h+1}}{2h+1}\sum _{i=1}^h \log\zeta(2i)\sum _{v=i}^{h}\frac{(-1)^{h-v}(4\pi )^{2h-2v}}{\zeta(2v-2i)(2h+2-2v)!} \text{, if }x\text{ is sufficiently large.}$ If you can let me know, and am willing to provide you with the typed out formula to be used in your math software. Notice this formula assumes 1 is not a prime (as it should.) The reasoning behind it can be found here. Last fiddled with by jrsousa2 on 2020-09-12 at 19:42

Very consistent.

The term "claim" appears to be more appropriate. Offhand, I see no reason to consider it, even if correct, as anything other than a curiosity. The claim is also poorly stated. The phrase "if x is sufficiently large" is entirely superfluous. The definition of asymptotic equality involves the limit as x increases without bound, or tends to plus infinity. Your request indicates to me that your series is difficult to evaluate. There are already expressions proven to be asymptotically equal to the prime-counting function, such as li(x) and x/log(x), which are easy to evaluate.

What are you taking the log of? If it's just the zeta, I don't get convergence. If it's the whole inner sum, what branch are you taking?
