[HTML][HTML] The approximation property for locally compact quantum groups
Abstract We study the Haagerup–Kraus approximation property for locally compact quantum
groups, generalising and unifying previous work by Kraus–Ruan and Crann. Along the way …

[HTML][HTML] Orthogonal free quantum group factors are strongly 1-bounded
M Brannan, R Vergnioux - Advances in Mathematics, 2018 - Elsevier
We prove that the orthogonal free quantum group factors L (FON) are strongly 1-bounded in
the sense of Jung. In particular, they are not isomorphic to free group factors. This result is …
