本文以Frobenius代数理论为基础,给出了一种统一的环论方法,得到了关于Hopf代数的一些结果.其中包括S.朱的程度不可约表示,所谓的类方程,确定的半单轨迹的Grothendieck环,频谱的伴随类和非零结果的伴随字符。
This expository article presents a unified ring theoretic approach, based on the theory of Frobenius algebras, to a variety of results on Hopf algebras. These include a theorem of S. Zhu on the degrees of irreducible representations, the so-called class equation, the determination of the semisimplicity locus of the Grothendieck ring, the spectrum of the adjoint class and a non-vanishing result for the adjoint character.
