What is the relationship between simple prime-power counting function and $logzeta(s)$?

$begingroup$


This question assumes the following definitions of prime-counting functions where $p$ denotes a prime number, $k$ denotes a positive integer, and $theta(y)$ is the Heaviside step function which takes a unit step at $y=0$.



(1) $quadpi(x)=sumlimits_{p}theta(x-p),qquadquadtext{(fundamental prime counting function)}$



(2) $quadPi(x)=sumlimits_{n=p^k}frac{1}{k},theta(x-n),quadtext{(Riemann's prime-power counting function)}$



(3) $quad k(x)=sumlimits_{n=p^k}theta(x-n),qquadtext{(simple prime-power counting function)}$





The following plot illustrates $pi(x)$, $Pi(x)$, and $k(x)$ in blue, orange, and green respectively. Note that $pi(x)$ takes a step of $1$ at each prime and $k(x)$ takes a step of $1$ at each prime-power. $Pi(x)$ is more complicated in that it takes a step of $frac{1}{k}$ at each prime-power $p^k$.





Illustration of Prime Counting Functions





The $pi(x)$ and $Pi(x)$ functions defined above are related to $logzeta(s)$ as defined below.



(4) $quadlogzeta(s)=sintlimits_0^inftyPi(x),x^{-s-1},dx,,quadRe(s)>1$



(5) $quadlogzeta(s)=sintlimits_0^inftyfrac{pi(x)}{x,left(x^s-1right)},dx,,qquadquadRe(s)>1$





Question: What is the relationship between $k(x)$ and $logzeta(s)$? More specifically, what is the definition of the function $f(x)$ consistent with (6) below?



(6) $quadlogzeta(s)=sintlimits_0^infty k(x),f(x),dx,,qquadquadRe(s)>1$





The following relationships between $pi(x)$, $Pi(x)$, and $k(x)$ may provide some insight where $rad(n)$ is the greatest square-free divisor of $n$ also referred to as the square-free kernel of $n$.



(7) $quadPi(x)=sumlimits_{n=1}^{log_2(x)}frac{1}{n},pi(x^{1/n})$



(8) $quadpi(x)=sumlimits_{n=1}^{log_2(x)}frac{mu(n)}{n},Pi(x^{1/n})$



(9) $quad k(x)=sumlimits_{n=1}^{log_2(x)}pi(x^{1/n})$



(10) $quadpi(x)=sumlimits_{n=1}^{log_2(x)}mu(n),k(x^{1/n})$



(11) $quad k(x)=sumlimits_{n=1}^{log_2(x)}frac{phi(n)}{n},Pi(x^{1/n})$



(12) $quadPi(x)=sumlimits_{n=1}^{log_2(x)}frac{mu(rad(n)),phi(rad(n))}{n},k(x^{1/n})$
