Spectral action on SU_q(2)

arXiv:0803.1058 · doi:10.1007/s00220-009-0810-8

Abstract

The spectral action on the equivariant real spectral triple over \A(SU_q(2)) is computed explicitly. Properties of the differential calculus arising from the Dirac operator are studied and the results are compared to the commutative case of the sphere S^3.
