Artin's Conjecture

There are at least two statements which go by the name of Artin's conjecture. The first is the Riemann Hypothesis. The second states that every Integer not equal to $-1$ or a Square Number is a primitive root modulo $p$ for infinitely many $p$ and proposes a density for the set of such $p$ which are always rational multiples of a constant known as Artin's Constant. There is an analogous theorem for functions instead of numbers which has been proved by Billharz (Shanks 1993, p. 147).
