Query: Twisted Dirac operator on quantum SU(2) in disc coordinates   The quantum disc is used to define a noncommutative analogue of a dense
coordinate chart and of left-invariant vector fields on quantum SU(2). This
yields two twisted Dirac operators for different twists that are related by a
gauge transformation and have bounded twisted commutators with a suitable
algebra of differentiable functions on quantum SU(2).
