Croissance asymptotique de nombres de Weil appartenant à un corps de nombres fixé

Abstract

We prove an asymptotic formula as $x\to +\infty$ for the number of algebraic integers $\alpha$ belonging to a fixed CM number field and satisfying $\alpha \overline{\alpha }\le x$. This problem is related to the height zeta function $Z_h(X^K,s)$ associated to the anticanonical class of a certain toric variety $X^K$ over $\mathbb{Q}$ and we show that $Z_h(X^K,s)$ has a meromorphic continuation to the half-plane $\{\Re (s)>\frac{1}{2}\}$ where it is holomorphic except at $s=1$. Along the way we obtain a new proof of Manin's conjecture on the asymptotic growth of points on $X^K(\mathbb{Q})$ of bounded height.
