zetafunction

mi idea or conjecture is that

\sum _{p} exp(-sp) = \sum_{n>0} \frac{P(-n)}{n!}(-1)^{n} s^{n}

where P(-n) are the regularized values of the sum

\sum _{p}p^{-s}= P(s) extended to negative (integers) value of 's'

if the sum where over integers instead of just over primes i believe

\sum _{0\le n } exp(-sn) = \sum_{n>0} \frac{\zeta(-n)}{n!}(-1)^{n} s^{n}

i got the inspiration looking at Euler-maclaurin summation formula.
