Gerstenhaber-Schack and Hochschild cohomologies of Hopf algebras
Julien Bichon
We show that the Gerstenhaber-Schack cohomology of a Hopf algebra determines its Hochschild cohomology, and in particular its Gerstenhaber-Schack cohomological dimension bounds its…

The group of bi-Galois objects over the coordinate algebra of the Frobenius-Lusztig kernel of SL(2)
Julien Bichon
We construct, for q a root of unity of odd order, an embedding of the projective special linear group PSL(n) into the group of bi-Galois objects over u_q(sl(n))*, the coordinate al…

Random walk questions for linear quantum groups
Teodor Banica, Julien Bichon
We study the discrete quantum groups whose group algebra has an inner faithful representation of type . Such a representation can be thought of as c…
