K-amenability of HNN extensions of amenable discrete quantum groups
We construct the HNN extension of discrete quantum groups, we study their representation theory and we show that an HNN extension of amenable discrete quantum groups... -

Approximation properties for discrete quantum groups
This dissertation is concerned with the notion of approximation property for discrete quantum groups and in particular weak amenability. Our goal is to apply... -

Fusion semiring of quantum groups
The purpose of this dissertation is to classify quantum groups according to invariants coming from their representation theory. More precisely, we classify Hopf... -
