Riemann Equivalence -- Reference sought
Can anyone supply me with a reference to the proof that the Riemann Hypothesis
is equivalent to the proof that for all n
prod(P(n))/phi(P(n)) > e^g * ln(ln(P(n))
where P(n) is the set comprised of the first n primes, phi is the Euler totient,
e is the Euler number and g is the Euler-Mascheroni constant?
It can be found, unreferenced, half way down this page -- Equivalence 3.2:
With thanks for any help.
