چکیده

– We classify pointed finite-dimensional complex Hopf algebras whose group of group-like elements is abelian of prime exponent p, p > 17. The Hopf algebras we find are members of a general family of pointed Hopf algebras we construct from Dynkin diagrams. As special cases of our construction we obtain all the Frobenius–Lusztig kernels of semisimple Lie algebras and their parabolic subalgebras. An important step in the classification result is to show that all these Hopf algebras are generated by group-like and skew-primitive elements.  2002 Éditions scientifiques et médicales Elsevier SAS RÉSUMÉ. – Nous classifions les algèbres de Hopf complexes de dimension finie dont le groupe des éléments groupoïdaux est abélien d’exposant premier p, p > 17. Les algèbres de Hopf que nous trouvons appartiennent à une famille d’algèbres de Hopf pointées que nous construisons à partir de diagrammes de Dynkin. Comme cas particuliers de notre construction nous obtenons tous les noyaux de Frobenius– Lusztig des algèbres de Lie semi-simples et leurs sous-algèbres paraboliques. Une étape importante dans notre classification consiste à montrer que toutes ces algèbres de Hopf sont engendrées par des éléments groupoïdaux et des éléments primitifs tordus.  2002 Éditions scientifiques et médicales Elsevier SAS

On the Exponent of Triple Tensor Product of p-Groups

The non-abelian tensor product of groups which has its origins in algebraic K-theory as well as inhomotopy theory, was introduced by Brown and Loday in 1987. Group theoretical aspects of non-abelian tensor products have been studied extensively. In particular, some studies focused on the relationship between the exponent of a group and exponent of its tensor square. On the other hand, com...

Finite Quantum Groups over Abelian Groups of Prime Exponent Nicolás Andruskiewitsch and Hans-jürgen Schneider

Since the discovery of quantum groups (Drinfeld, Jimbo) and finite dimensional variations thereof (Lusztig, Manin), these objects were studied from different points of view and had many applications. The present paper is part of a series where we intend to show that important classes of Hopf algebras are quantum groups and therefore belong to Lie theory. One of our main results is the explicit ...

Quantum Error-Correction Codes on Abelian Groups

We prove a general form of bit flip formula for the quantum Fourier transform on finite abelian groups and use it to encode some general CSS codes on these groups.

On solving systems of random linear disequations

An important subcase of the hidden subgroup problem is equivalent to the shift problem over abelian groups. An efficient solution to the latter problem would serve as a building block of quantum hidden subgroup algorithms over solvable groups. The main idea of a promising approach to the shift problem is reduction to solving systems of certain random disequations in finite abelian groups. The r...

2-recognizability of the simple groups $B_n(3)$ and $C_n(3)$ by prime graph

Let $G$ be a finite group and let $GK(G)$ be the prime graph of $G$. We assume that $ngeqslant 5 $ is an odd number. In this paper, we show that the simple groups $B_n(3)$ and $C_n(3)$ are 2-recognizable by their prime graphs. As consequences of the result, the characterizability of the groups $B_n(3)$ and $C_n(3)$ by their spectra and by the set of orders of maximal abelian subgroups are ...
