nLab differential graded ring




A differental graded ring or dg-ring is a monoid in the category of chain complexes or of cochain complexes of abelian groups.

If a dg-ring is degreewise compatibly a vector space (or more generally a module over some ring) then it is called dg-algebra. See there for more.
