Algebraic quantum permutation groups
Julien Bichon
We discuss some algebraic aspects of quantum permutation groups, working over arbitrary fields. If is any characteristic zero field, we show that there exists a universal cosem…

Quantum groups acting on 4 points
Teodor Banica, Julien Bichon
We classify the compact quantum groups acting on 4 points. These are the quantum subgroups of the quantum permutation group . Our main tool is a new presentation for…

The hyperoctahedral quantum group
Teodor Banica, Julien Bichon, Benoit Collins
We consider the hypercube in , and show that its quantum symmetry group is a -deformation of at . Then we consider the graph formed by segments, and…
