摘要:The aim of this talk is to summarize the advances of the last three decades on the classification of finite-dimensional pointed Hopf algebras, starting from the basic definitions. We will recall concepts like the coradical filtration, the Lifting method and cocycle deformations which will allow us to describe the full classification in the case that the coradical is the group algebra of an abelian group, and state the solutions and open problems towards the non abelian case. We aim to finish describing other related classification problems, as the one on finite pointed tensor categories.
报告人简介:Ivan Angiono现任阿根廷科尔多瓦国立大学(UNC)教授、阿根廷国家科学技术研究委员会(CONICET)独立研究员,是Hopf代数与张量范畴领域的国际权威学者。他长期深耕Nichols代数与点化Hopf代数的结构与分类理论,在有限维及具有有限GK维数的无限维点化Hopf代数的分类研究中处于国际领先地位。他在该领域核心公开性问题——Andruskiewitsch-Schneider猜想的研究上取得了突破性进展,并在张量范畴、李(超)代数及其数学物理应用等方面贡献卓著。Angiono教授现担任《Journal of Pure and Applied Algebra》等顶级代数期刊编委,并获邀在2026年国际数学家大会(ICM)作45分钟邀请报告。
