Non-commutative 4-spheres based on all Podleś 2-spheres and beyond
arXiv:math/0101129
Abstract
A wide class of noncommutative spaces, including 4-spheres based on all the quantum 2-spheres and suspensions of matrix quantum groups is described. For each such space a noncommutative vector bundle is constructed. This generalises and clarifies various recent constructions of noncommutative 4-spheres.
