From Hopf C*-families to concrete Hopf C*-bimodules
Thomas Timmermann
In the setting of von Neumann algebras, measurable quantum groupoids have successfully been axiomatized and studied by Enock, Vallin, and Lesieur, whereas in the setting of …
Finite-dimensional Hopf C*-bimodules and C*-pseudo-multiplicative unitaries
Thomas Timmermann
Finite quantum groupoids can be described in many equivalent ways: In terms of the weak Hopf C*-algebras of Böhm, Nill, and Szlachányi or the finite-dimensional Hopf-von Neumann bi…
-pseudo-Kac systems and duality for coactions of concrete Hopf -bimodules
Thomas Timmermann
We study coactions of concrete Hopf -bimodules in the framework of (weak) -pseudo-Kac systems, define reduced crossed products and dual coactions, and prove an analog…
C*-pseudo-multiplicative unitaries
Thomas Timmermann
We introduce -pseudo-multiplicative unitaries and (concrete) Hopf -bimodules, which are -algebraic variants of the pseudo-multiplicative unitaries on Hilbert spaces…
