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…

Notes on gamma invariants of finite dimensional Hopf algebras

Xinru Zhang, Libin Li, Yinhuo Zhang

Let $H$ be a finite-dimensional, non-semisimple Hopf algebra over an algebraically closed field $k$ . This paper investigates the asymptotic behavior of the core of left $H…

The Projective Class Rings of Drinfeld doubles of pointed rank one Hopf algebras

Hua Sun, Hui-Xiang Chen, Libin Li +1

Let $k$ be an algebraically closed field of characteristic $0$ . In this paper, we study the Grothendieck ring $G_{0} (D (H_{D}))$ and the projective class ring $r_p(D(H_\ma…

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…

Representations of the Drinfeld doubles of Pointed rank one Hopf algebras

Hua Sun, Huixiang Chen, Yinhuo Zhang

In this paper, we investigate the representations of the Drinfeld doubles $D (H_{D})$ of pointed rank one Hopf algebras $H_{D}$ over an algebraically closed fiel…

Affineness on Noetherian graded rings, algebras and Hopf algebras

Huan Jia, Yinhuo Zhang

In this note, we show that every Noetherian graded ring with an affine degree zero part is affine. As a result, a Noetherian graded Hopf algebra whose degree zero component is a co…
