Derived invariance of the cap product in Hochschild theory
[Invariance dérivée du cap produit en théorie de Hochschild]
Comptes Rendus. Mathématique, Volume 355 (2017) no. 12, pp. 1205-1207.

Nous démontrons l'invariance dérivée du cap produit pour les algèbres associatives projectives sur un anneau commutatif.

We prove the derived invariance of the cap product for associative algebras projective over a commutative ring.
