Prime product formulas for the Riemann zeta function and related identities

Abstract

In this article, we derive a Euler prime product formula for the magnitude of the Riemann zeta function $\zeta(s)$ valid for $\Re(s)>1$, as well as similar formulas for $\zeta(s)$ valid for an even and odd $k$th positive integer argument. We shall further give a set of generated formulas for $\zeta(k)$ up to $11$th order, including Ap\'ery's constant, and also construct formulas for $\zeta(3/2)$. We'll also validate these formulas numerically.
