Query: A torsion theory in the category of cocommutative Hopf algebras   The purpose of this article is to prove that the category of cocommutative
Hopf $K$-algebras, over a field $K$ of characteristic zero, is a semi-abelian
category. Moreover, we show that this category is action representable, and
that it contains a torsion theory whose torsion-free and torsion parts are
given by the category of groups and by the category of Lie $K$-algebras,
respectively.
