Chern numbers for two families of noncommutative Hopf fibrations

Piotr M. Hajac, Rainer Matthes, Wojciech Szymanski

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 a…

Quantum Real Projective Space, Disc and Sphere

Piotr M. Hajac, Rainer Matthes, Wojciech Szymanski

We define the $C^{*}$ -algebra of quantum real projective space $R P_{q}^{2}$ , classify its irreducible representations and compute its $K$ -theory. We also show that the $q$ -disc of Klim…

Frame, cotangent and tangent bundles of the quantum plane

P. M. Hajac, R. Matthes

We construct a quantum frame bundle of the quantum plane $C_{p}^{2}$ by requiring that a $G L_{q, p} (2)$ -covariant differential calculus on $C_{p}^{2}$ be isomorphic as a bimodule to the spa…
