Abstract
Let H be a coquasi-triangular Hopf algebra. We first show that the group of braided autoequivalences of the category of H-comodules is isomorphic to the group of braided-commutative bi-Galois objects. Next, by investigating the latter, we obtain that the group of braided autoequivalences of the representation category of Lusztig's quantum group uq(sl(2))â² is isomorphic to the projective special linear group PSL(2), where q is a root of unity of odd order N>1.
