Is this product convergent

    Following Euler if we define the product:

    [tex] (x-2^{-s})(x-3^{-s}) (x-5^{-s})(x-7^{-s}).......=f(x) [/tex]

    taken over all primes and s > 1 ,what would be the value of f(x) ?? i believe that [tex] f(x,s)=1/Li_{s} (x) [/tex] (inverse of Polylogarithm) however i'm not 100 % sure, although for x=1 you get the inverse of Riemann Zeta

    1. Inverse and Reciprocals aren't the same thing.

    2. For any value of s, and x > 1, the terms do not approach 1, but x. x being more than 1, the terms are not approaching 1, so the product does not converge.
