On actions of ℂ * on algebraic spaces
Annales de l'Institut Fourier, Tome 43 (1993) no. 2, pp. 359-364.

Le résultat principal de cet article est la constatation que tous les points schématiques de la source d’une action de C * sur un espace algébrique X sont schématiques sur X.

The main result of the paper says that all schematic points of the source of an action of C * on an algebraic space X are schematic on X.
