Rongchuan Xiong

TL;DR
This paper classifies certain finite-dimensional Hopf algebras over algebraically closed fields of characteristic zero, focusing on those with a specific basic Hopf algebra of dimension 24 as the coradical and indecomposable infinitesimal braidings.
Contribution
It provides a classification of new finite-dimensional Hopf algebras with a given coradical structure, including examples without the dual Chevalley property.
Findings
Identification of families of new Hopf algebras
Construction of examples lacking the dual Chevalley property
Extension of classification results to non-pointed cases
Abstract
We determine finite-dimensional Hopf algebras over an algebraically closed field of characteristic zero, whose Hopf coradical is isomorphic to a non-pointed basic Hopf algebra of dimension and the infinitesimal braidings are indecomposable objects. In particular, we obtain families of new finite-dimensional Hopf algebras without the dual Chevalley property.
