On the classification of Galois objects over the quantum group of a   nondegenerate bilinear form
  We study Galois and bi-Galois objects over the quantum group of a nondegenerate bilinear form, including the quantum group Oq(SL2). We obtain the classification of these objects up to isomorphism and some partial results for their classification up to homotopy.
