A commutative and cocommutative Hopf algebra in nature

Branko Nikolic – 28 June 2017

Chain complexes of Abelian groups can be obtained as (co)algebras for different (co)monads. We compare Pareigis' non-(co)commutative Hopf algebra approach (1980) with our (co)-commutative one, and then provide two general constructions applicable to (braided) monoidal additive categories.
