Primitive cohomology of Hopf algebras

DG Wang, JJ Zhang, G Zhuang - Journal of Algebra, 2016 - Elsevier
Primitive cohomology of a Hopf algebra is defined by using a modification of the cobar
construction of the underlying coalgebra. Among many of its applications, two classifications …

[HTML][HTML] Classification of connected Hopf algebras of dimension p3 I

VC Nguyen, L Wang, X Wang - Journal of Algebra, 2015 - Elsevier
Let p be a prime, and k be an algebraically closed field of characteristic p. In this paper, we
provide the classification of connected Hopf algebras of dimension p 3, except for the case …

Iterated Hopf Ore extensions in positive characteristic

KA Brown, JJ Zhang - J. Noncommut. Geom., 2022 - ems.press
Iterated Hopf Ore extensions (IHOEs) over an algebraically closed base field k of positive
characteristic p are studied. We show that every IHOE over k satisfies a polynomial identity …

Hopf algebras of prime dimension in positive characteristic

SH Ng, X Wang - Bulletin of the London Mathematical Society, 2019 - Wiley Online Library
We prove that a Hopf algebra of prime dimension p over an algebraically closed field, whose
characteristic is equal to p, is either a group algebra or a restricted universal enveloping …

Classification of Pointed Hopf Algebras of Dimension p 2 over any Algebraically Closed Field

L Wang, X Wang - Algebras and Representation Theory, 2014 - Springer
Let p be a prime. We complete the classification of pointed Hopf algebras of dimension p 2
over an algebraically closed field k. When char k≠ p, our result is the same as the well …

Finite Symmetric Integral Tensor Categories with the Chevalley Property with an Appendix by Kevin Coulembier and Pavel Etingof

P Etingof, S Gelaki - International Mathematics Research Notices, 2021 - academic.oup.com
We prove that every finite symmetric integral tensor category with the Chevalley property
over an algebraically closed field of characteristic admits a symmetric fiber functor to the …

Enriques surfaces with normal K3-like coverings

S Schröer - Journal of the Mathematical Society of Japan, 2021 - jstage.jst.go.jp
We analyze the structure of simply-connected Enriques surfaces in characteristic two whose
K3-like coverings are normal, building on the work of Ekedahl, Hyland and Shepherd …

Primitive Deformations of Quantum p-Groups

VC Nguyen, L Wang, X Wang - Algebras and Representation Theory, 2019 - Springer
In this paper, working over an algebraically closed field k of prime characteristic p, we
introduce a concept, called Primitive Deformation, to provide a structured technique to …

On Hopf algebras of dimension in characteristic

SH Ng, X Wang - arXiv preprint arXiv:2308.10471, 2023 - arxiv.org
Let $\Bbbk $ be an algebraically closed field of characteristic $ p> 0$. We study the general
structures of $ p^ n $-dimensional Hopf algebras over $\Bbbk $ with $ p^{n-1} $ group-like …

S Schröer - arXiv preprint arXiv:1703.03081, 2017 - arxiv.org
We analyze the structure of simply-connected Enriques surface in characteristic two whose
K3-like covering is normal, building on the work of Ekedahl, Hyland and Shepherd-Barron …
