摘要: Abstract We show that the representation category of quantum group a non-degenerate bilinear form is monoidally equivalent to SL q (2) for well chosen non-zero parameter q. The key ingredient proof this result direct and explicit construction an appropriate Hopf bigalois extension. Then we get, when base field characteristic zero, full description cosemisimple algebras whose semi-ring isomorphic one SL(2).
