Abstract

Derived A–algebras were developed recently by Sagave. Their advantage over classical A–algebras is that no projectivity assumptions are needed to study minimal models of differential graded algebras. We explain how derived A–algebras can be viewed as algebras over an operad. More specifically, we describe how this operad arises as a resolution of the operad dAs encoding bidgas, ie bicomplexes with an associative multiplication. This generalises the established result describing the operad A as a resolution of the operad As encoding associative algebras. We further show that Sagave’s definition of morphisms agrees with the infinity-morphisms of dA–algebras arising from operadic machinery. We also study the operadic homology of derived A–algebras.
