Finite-dimensional Nichols algebras over dual Radford algebras

Dirceu Bagio, Gastón A. García, João M. J. Giraldi +1

For $n,m\in \mathbb{N}$, let $H_{n,m}$ be the dual of the Radford algebra of dimension $n^{2}m$. We present new finite-dimensional Nichols algebras arising from the study of simple…
