Values of the prime zeta function at rational numbers
For $\Re(s)>1$, one defines $P(s) = \sum_{p\in \text{primes}} p^{-s}$, which can be analytically continued to $\Re(s)>0$. This list contains values $P(s)$ for certain rational numbers $s$.
Parameters
$s$
— complex number ($\Re(s) > 0$, $s$ not the inverse of a squarefree integer)
Comments
(1)
$P(s)$ has its poles at $1/n$, where $n$ runs over all squarefree positive integers.
Programs
(P1)
Sage
from mpmath import mp
numbers = {a/b: mp.primezeta(a/b)
for b,a in cartesian_product(([1..20],[1..20]))
if gcd(a,b) == 1 and a/b != 1 and
(a != 1 or not b.is_squarefree())}
