In this paper we compute the integral Chow ring of the stack of smooth uniform cyclic covers of the projective line and we give explicit generators.
Dans ce travail nous calculons l’anneau d’intersection avec des coef- ficients entiers du champ des revêtements cycliques lisses et uniformes de la droite projective. Nous explicitons aussi tous les générateurs.
Keywords: Intersection theory, cyclic covers, algebraic stacks, moduli stacks of curves
Mot clés : théorie de l’intersection, revêtements cycliques, champs algébriques, champs de modules des courbes
