The Tannaka–Krein Formalism and (Re)Presentations of Universal Quantum Groups
Book Contribution - Chapter
In this chapter we expand upon Section 14.8 of the present volume, where the possibility of “hidden symmetry” in algebraic geometry was discussed. More precisely, our goal is to convince the reader that, as long as one starts with a reasonable algebra A, the universal bi- and Hopf algebras end(A) and gl(A) introduced in Chapters 5 and 8 are well-behaved objects.
