Abstract:
Let (Γ, d) be the 3D-calculus or the 4D±-calculus on the quantum group SUq (2). We describe all pairs (π, F) of a *-representation π of (SUq(2)) and of a symmetric operator F on the representation space satisfying a technical condition concerning its domain such that there exist a homomorphism of first order differential calculi which maps dx into the commutator [iF, π(x)] for x ε (SUq (2)). As an application commutator representations of the two-dimensional left-covariant calculus on Podles quantum 2-sphere Sqc2 with c = 0 are given.
