Restricted Lie Algebras via Monadic Decomposition
- 58 Downloads
We give a description of the category of restricted Lie algebras over a field \(\Bbbk \) of prime characteristic by means of monadic decomposition of the functor that computes the \(\Bbbk \)-vector space of primitive elements of a \(\Bbbk \)-bialgebra.
