On Classification of Finite-dimensional Semisimple Hopf Algebras
نویسنده
چکیده
We develop a mechanism for classication of isomorphism types of non-trivial semisimple Hopf algebras whose group of grouplikes G(H) is abelian of prime index p which is the smallest prime divisor of |G(H)|. We describe structure of the second cohomology group of extensions of kCp by k G where Cp is a cyclic group of order p and G a finite abelian group. We carry out an explicit classification for Hopf algebras of this kind of dimension p for any odd prime p. The ground field is algebraically closed of characteristic 0.

THE NICHOLS ALGEBRA OF A SEMISIMPLE YETTER-DRINFELD MODULE By NICOLÁS ANDRUSKIEWITSCH, ISTVÁN HECKENBERGER, and HANS-JÜRGEN SCHNEIDER
We study the Nichols algebra of a semisimple Yetter-Drinfeld module and introduce new invariants including the notions of real roots and the Weyl groupoid. The crucial ingredient is a “reflection” defined on arbitrary such Nichols algebras. Our construction generalizes the restriction of Lusztig’s automorphisms of quantized Kac-Moody algebras to the nilpotent part. As a direct application we co...
متن کاملA Method of Construction of Finite-dimensional Triangular Semisimple Hopf Algebras
The goal of this paper is to give a new method of constructing finite-dimensional semisimple triangular Hopf algebras, including minimal ones which are non-trivial (i.e. not group algebras). The paper shows that such Hopf algebras are quite abundant. It also discovers an unexpected connection of such Hopf algebras with bijective 1-cocycles on finite groups and set-theoretical solutions of the q...
متن کاملHopf Algebras of Dimension
Let H be a finite-dimensional Hopf algebra over an algebraically closed field of characteristic 0. If H is not semisimple and dim(H) = 2n for some odd integers n, then H or H * is not unimodular. Using this result, we prove that if dim(H) = 2p for some odd primes p, then H is semisimple. This completes the classification of Hopf algebras of dimension 2p. In recent years, there has been some pro...

متن کاملForms of Coalgebras and Hopf Algebras
We study forms of coalgebras and Hopf algebras (i.e. coalgebras and Hopf algebras which are isomorphic after a suitable extension of the base field). We classify all forms of grouplike coalgebras according to the structure of their simple subcoalgebras. For Hopf algebras, given a W ∗-Galois field extension K ⊆ L for W a finite-dimensional semisimple Hopf algebra and a K-Hopf algebra H, we show ...
متن کاملOn Finite-dimensional Semisimple and Cosemisimple Hopf Algebras in Positive Characteristic
Recently, important progress has been made in the study of finite-dimensional semisimple Hopf algebras over a field of characteristic zero [Mo and references therein]. Yet, very little is known over a field of positive characteristic. In this paper we prove some results on finite-dimensional semisimple and cosemisimple Hopf algebras A over a field of positive characteristic, notably Kaplansky’s...
