Differential Calculus on Quantum Spheres
Martin Welk
Abstract
We study covariant differential calculus on the quantum spheres Sq2N-1. Two classification results for covariant first order differential calculi are proved. As an important step towards a description of the noncommutative geometry of the quantum spheres, a framework of covariant differential calculus is established, including a particular first order calculus obtained by factorization, higher order calculi and a symmetry concept.
