Abstract
Following Bernhard Keller [13], a differential Z -graded O-algebra or, in short, a D-algebra is an O-algebra A endowed with a differential Z-graded O-module structure (see Remark 10.5 above) such that the product map A ⊗o A → A is D-linear or, equivalently, such that, for any a, a’ ∈ A and any ∈ℱ,we have (cf. 10.2.3)
