Podleś' Quantum Sphere: Dual Coalgebra and Classification of Covariant First Order Differential Calculus
I. Heckenberger, S. Kolb
Abstract
The dual coalgebra of Podleś' quantum sphere Oq(S2c) is determined explicitly. This result is used to classify all finite dimensional covariant first order differential calculi over Oq(S2c) for all but exceptional values of the parameter c.
