Quantum direct products and the Künneth class
Rubén Martos
We introduce a Künneth class in the quantum equivariant setting inspired by the pioneer work by J. Chabert, H. Oyono-Oyono and S. Echterhoff, which allows to relate the quantum Bau…
Permanence of the torsion-freeness property for divisible discrete quantum subgroups
Rubén Martos
We prove that torsion-freeness in the sense of Meyer-Nest is preserved under divisible discrete quantum subgroups. As a consequence, we obtain some stability results of the torsion…
Projective representation theory for compact quantum groups and the quantum Baum-Connes assembly map
Kenny De Commer, Rubén Martos, Ryszard Nest
We study the theory of projective representations for a compact quantum group , i.e. actions of on for some Hilbert space . We show tha…
Torsion and K-theory for some free wreath products
Amaury Freslon, Rubén Martos
We classify torsion actions of free wreath products of arbitrary compact quantum groups and use this to prove that if is a torsion-free compact quantum group satisfyin…
The Baum-Connes property for a quantum (semi-)direct product
Rubén Martos
The well known "associativity property" of the crossed product by a semi-direct product of discrete groups is generalized into the context of discrete \emph{quantum} groups. This d…
