The Tannaka-Krein formalism and (re)presentations of universal quantum groups
arXiv:1806.02758
Abstract
This is a draft version for an extra chapter in the second edition of the book Quantum Groups and Noncommutative Geometry by Yu. I. Manin. We survey our work on Manin's universal Hopf algebras, placing particular emphasis on the Tannaka-Krein formalism.
