Beurling-Fourier algebras of -deformations of compact semisimple Lie groups and complexification
Heon Lee, Christian Voigt
We study Beurling-Fourier algebras of -deformations of compact semisimple Lie groups. In particular, we show that the space of irreducible representations of the function alge…

Averaging multipliers on locally compact quantum groups
Matthew Daws, Jacek Krajczok, Christian Voigt
We study an averaging procedure for completely bounded multipliers on a locally compact quantum group with respect to a compact quantum subgroup. As a consequence we show that cent…
