Prépublications : [arxiv] A-upper motives with Nikita Karpenko and Anne Quéguiner-Mathieu [arxiv] Higher Tate traces of Chow motives with Anne Quéguiner-Mathieu [arxiv] Smooth Profinite Groups, I: Geometrizing Kummer Theory            with Mathieu Florence [arxiv] Smooth Profinite Groups, III: The Smoothness Theorem            with Mathieu Florence The proofs of Smooth Profinite Groups I and III have been checked, but III uses statements from Smooth Profinite Groups II whose proof contain a gap. Therefore, the series thus not provide a complete proof of the smoothness conjecture, for the moment. We hope to fix this soon.
