Abstract

We consider Artin's conjecture on primitive roots over a number field K $K$ , reducing an algebraic number α K × $\alpha \in K^\times$ . Under the Generalised Riemann Hypothesis, there is a density dens ( α ) $\operatorname{dens}(\alpha)$ counting the proportion of the primes of K $K$ for which α $\alpha$ is a primitive root. This density dens ( α ) $\operatorname{dens}(\alpha)$ is a rational multiple of an Artin constant A ( τ ) $A(\tau)$ that depends on the largest integer τ 1 $\tau \geqslant 1$ such that α K × τ $\alpha \in {\left(K^\times \right)}^\tau$ . The aim of this paper is bounding the ratio dens ( α ) / A ( τ ) $\operatorname{dens}(\alpha)/A(\tau)$ , under the assumption that dens ( α ) 0 $\operatorname{dens}(\alpha)\ne 0$ . Over Q $\mathbb {Q}$ , this ratio is between 2 / 3 $2/3$ and 2, these bounds being optimal. For a general number field K $K$ , we provide upper and lower bounds that only depend on K $K$ .
