Hopf fibration and monopole connection over the contact quantum spheres
Tomasz Brzezinski, Ludwik Dabrowski, Bartosz Zielinski
Abstract
Noncommutative geometry of quantised contact spheres introduced by Omori, Maeda, Miyazaki and Yoshioka is studied. In particular it is proven that these spheres form a noncommutative Hopf fibration in the sense of Hopf-Galois extensions. The monopole (strong) connection is constructed, and projectors describing projective modules of all monopole charges are computed.
