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…

The Ribbon Elements of Drinfeld Double of Radford Hopf Algebra

Hua Sun, Yuyan Zhang, Libin Li

Let $m$ , $n$ be two positive integers, $k$ be an algebraically closed field with char( $k) ∤ mn$ . Radford constructed an $m n^{2}$ -dimensional Hopf algebra $R_{mn} (q)$ suc…
