Derivations and non-commutative differential calculus. II. (Dérivations et calcul différentiel non commutatif. II.) (French. Abridged English version) Zbl 0829.16028
Let $$A$$ be an associative algebra over $$\mathbb{R}$$ or $$\mathbb{C}$$ with a unit. In part I [M. Dubois-Violette, ibid. 307, 403-408 (1988; Zbl 0661.17012)] the notion of a graded differential algebra $$\Omega_{\text{Der}(A)}$$ was introduced. One of the aims of this note is to show that, by introducing a new category of bimodules, the derivation $$d: A \to \Omega^1_{\text{Der} (A)}$$ is characterized by a universal property.
