Chern numbers for two families of noncommutative Hopf fibrations
We consider noncommutative line bundles associated with the Hopf fibrations
of SUq(2) over all Podles spheres and with a locally trivial Hopf fibration of
S^3_{pq}. These bundles are given as finitely generated projective modules
associated via 1-dimensional representations of U(1) with Galois-type
extensions encoding the principal fibrations of SUq(2) and S^3_{pq}. We show
that the Chern numbers of these modules coincide with the winding numbers of
representations defining them.Comment: 6 page
