(Non-Symmetric) Yetter–Drinfel’d Module Category and Invariant Coinvariant Jacobians

Abstract

In this paper, we generalize the homomorphisms of modules over groups and Lie algebras as being morphisms in the category of (non-symmetric) Yetter–Drinfel’d modules. These module homomorphisms play a key role in the conjecture of Yau.
