Hypersurfaces quartiques de dimension 3 : non rationalité stable

preprint2015arXivOpen access

Abstract

Inspirés par un argument de C. Voisin, nous montrons l'existence d'hypersurfaces quartiques lisses dans PC4{\bf P}^4_{\mathbb C} qui ne sont pas stablement rationnelles, plus précisément dont le groupe de Chow de degré zéro n'est pas universellement égal à Z\mathbb Z. --- There are (many) smooth quartic hypersurfaces in PC4{\bf P}^4_{\mathbb C} which are not stably rational. More precisely, their degree zero Chow group is not universally equal to Z\mathbb Z. The proof uses a variation of a specialisation method due to C. Voisin.
