Can this be the solution for composites?


It is well known by the standard Riemann Zeta function that

ζ(s)=n=11ns \zeta (s) = \displaystyle \sum_{n=1}^{\infty} \dfrac{1}{n^s}

For R(s)>1 \mathfrak{R} (s) > 1 .

Also, the Prime Zeta function gives us

P(s)=p1ps P(s) = \displaystyle \sum_{p} \dfrac{1}{p^s}

For p{primes}p \in \{ \text{primes} \} and R(s)>1 \mathfrak{R} (s) > 1 .


This means that the sum of sths^{\text{th}} powers of the reciprocals of all composite numbers can be given by the formula

P(s)=p1ps=n=11nsp1ps1=ζ(s)P(s)1 \begin{aligned} P'(s) &= \displaystyle \sum_{p'} \dfrac{1}{{p'}^s} \\ &= \sum_{n=1}^{\infty} \dfrac{1}{n^s} - \sum_{p} \dfrac{1}{p^s} - 1 \\ &= \zeta (s) - P(s) - 1 \end{aligned}

For p{composite numbers}p' \in \{ \text{composite numbers} \} and R(s)>1 \mathfrak{R} (s) > 1 .

Knowing that infinite sums are risky to handle. I would like your opinions on whether the conclusion drawn from the two given true propositions made above are correct or not.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

if un,vnu_n,v_n are convergent sequences then so is their difference. Provided ζ(s),P(s)\zeta(s),P(s) converges which is obvious ,your conclusions are true enough
