The full classification of orthogonal easy quantum groups
Sven Raum, Moritz Weber
In 1987, Woronowicz gave a definition of compact matrix quantum groups generalizing compact Lie groups in the setting of noncommutative geometry. About twenty years later, Banica a…
The combinatorics of an algebraic class of easy quantum groups
Sven Raum, Moritz Weber
Easy quantum groups are compact matrix quantum groups, whose intertwiner spaces are given by the combinatorics of categories of partitions. This class contains the symmetric group…
Easy quantum groups and quantum subgroups of a semi-direct product quantum group
Sven Raum, Moritz Weber
We consider compact matrix quantum groups whose fundamental corepresentation matrix has entries which are partial isometries with central support. We show that such quantum groups…
Baumslag-Solitar groups, relative profinite completions and measure equivalence rigidity
Cyril Houdayer, Sven Raum
We introduce an algebraic invariant for aperiodic inclusions of probability measure preserving equivalence relations. We use this invariant to prove that every stable orbit equival…
