“Quantum group-twisted tensor product of C*-algebras”
We put two C*-algebras together in a noncommutative tensor product using quantum group actions on them and a bicharacter relating the two quantum groups that act. We describe this twisted tensor product, generalising minimal tensor product of C*-algebras, in two equivalent ways, based on certain pairs of quantum group representations and based on covariant Hilbert space representations, respectively.
This is a joint work with Ralf Meyer and Stanislaw Lech Woronowcz.
