A graded-cocommutative codifferential coalgebra is a cocommutative comonoid in the category of chain complexes (of modules over some ring).
We write for the category of such codifferential coalgebras.
- Codifferential coalgebras whose underlying graded-cocommutative coalgebra is free over a complex of vector spaces in positive degree are Lie infinity-algebras.
