The Dirac Operator on SUq(2)

We construct a 3+-summable spectral triple [inline-graphic not available: see fulltext] over the quantum group SUq(2) which is equivariant with respect to a left and a right action of [inline-graphic not available: see fulltext] The geometry is isospectral to the classical case since the spectrum of the operator D is the same as that of the usual Dirac operator on the 3-dimensional round sphere. The presence of an equivariant real structure J demands a modification in the axiomatic framework of spectral geometry, whereby the commutant and first-order properties need be satisfied only modulo infinitesimals of arbitrary high order.
