Tracing the orbitals of the quantum permutation group

J. P. McCarthy

Using a suitably noncommutative flat matrix model, it is shown that the quantum permutation group has free orbitals: that is, a monomial in the generators of the algebra of functio…

Analysis for idempotent states on quantum permutation groups

J. P. McCarthy

Woronowicz proved the existence of the Haar state for compact quantum groups under a separability assumption later removed by Van Daele in a new existence proof. A minor adaptation…

The Frucht property in the quantum group setting

Teo Banica, J. P. McCarthy

A classical theorem of Frucht states that any finite group appears as the automorphism group of a finite graph. In the quantum setting the problem is to understand the structure of…
