Query: Representations of quantum SU(2) operators on a local chart   Hilbert space representations of quantum SU(2) by multiplication operators on
a local chart are constructed, where the local chart is given by tensor
products of square integrable functions on a quantum disc and on the classical
unit circle. The actions of generators of quantum SU(2), generators of the
opposite algebra, and noncommutative partial derivatives are computed on a
Hilbert space basis.
