A Noetherian Hopf algebra is affine iff its Hopf coradical is affine

Huan Jia, Yinhuo Zhang

Let $\K$ denote a field. Extending the structural frameworks established in \cite{JZ2025-2}, this paper introduces novel techniques utilizing non-commutative reduction orders, fact…

Noetherian pointed Hopf algebras are affine

Huan Jia, Yinhuo Zhang

Let $k$ be a field. In this paper, we introduce the notions of $reduction order$ and $reduction-factorization$ on words, and use them to show that any right or le…
