A compositional approach to quantum functions
We introduce a notion of quantum function and develop a compositional framework for finite
quantum set theory based on a 2-category of quantum sets and quantum functions. We use …

[HTML][HTML] Closed quantum subgroups of locally compact quantum groups
We investigate the fundamental concept of a closed quantum subgroup of a locally compact
quantum group. Two definitions—one due to S. Vaes and one due to SL Woronowicz—are …

Hopf images and inner faithful representations
T Banica, J Bichon - Glasgow Mathematical Journal, 2010 - cambridge.org
We develop a general theory of Hopf image of a Hopf algebra representation, with the
associated concept of inner faithful representation, modelled on the notion of faithful …

Reduced operator algebras of trace-preserving quantum automorphism groups
M Brannan - Documenta Mathematica, 2013 - content.ems.press
Let B be a finite dimensional C∗-algebra equipped with its canonical trace induced by the
regular representation of B on itself. In this paper, we study various properties of the trace …

Quantum automorphisms of folded cube graphs
S Schmidt - Annales de l'Institut Fourier, 2020 - numdam.org
The concept of quantum automorphism groups of finite graphs was introduced by Banica
and Bichon in [1, 9]. It generalizes the classical automorphism groups of graphs within the …

[HTML][HTML] Quantum binary polyhedral groups and their actions on quantum planes
We classify quantum analogues of actions of finite subgroups G of SL 2(k) on commutative
polynomial rings k[u, v]. More precisely, we produce a classification of pairs (H, R) where H …

[HTML][HTML] Flat matrix models for quantum permutation groups
We study the matrix models π: C (S N+)→ MN (C (X)) which are flat, in the sense that the
standard generators of C (S N+) are mapped to rank 1 projections. Our first result is a …
