Models of quantum permutations

Stefan Jung, Moritz Weber

For $N \geq 4$ we present a series of *-homomorphisms $φ_{n} : C (S_{N}^{+}) \to B_{n}$ where $S_{N}^{+}$ is the quantum permutation group. They are not necessarily representations of the qu…

Partition quantum spaces

Stefan Jung, Moritz Weber

We propose a definition of partition quantum spaces. They are given by universal $C^{*}$ -algebras whose relations come from partitions of sets. We ask for the maximal compact matrix…

Partition C*-algebras II - Links to Compact Matrix Quantum Groups

Moritz Weber

In a recent article, we gave a definition of partition C*-algebras. These are universal C*-algebras based on algebraic relations which are induced from partitions of sets. In this…

Partition C*-algebras

Moritz Weber

We give a definition of partition C*-algebras: To any partition of a finite set, we assign algebraic relations for a matrix of generators of a universal C*-algebra. We then prove h…

On C*-Algebras Generated by Isometries with Twisted Commutation Relations

Moritz Weber

In the theory of C*-algebras, interesting noncommutative structures arise as deformations of the tensor product. For instance, the rotation algebra may be seen as a scalar twist de…
