Galois reconstruction of finite quantum groups
arXiv:math/9906103
Abstract
We describe a universal factorization for a functor with values in finite-dimensional measured algebras. More precisely we contruct the quantum automorphism group of this functor. This general recontruction result allows us to recapture a finite-dimensional Hopf algebra from the category of finite-dimensional measured comodule algebras.
