Cohomologies bivariantes de type cyclique
In the article we propose a construction of bivariant cohomology of a couple of chain complexes with periodicities. In this way we obtain definitions of bivariant dihedral and bivariant reflective cohomology of an algebra . Bivariant cyclic and quaternionic cohomologies appear as particular cases of this construction. The case of invertible in the ground ring is studied particulary. Dans cet article nous proposons une définition de la cohomologie bivariante pour une paire de complexes...
