Podle\'s' Quantum Sphere: Dual Coalgebra and Classification of Covariant First Order Differential Calculus
The dual coalgebra of Podle\'s' quantum sphere O_q(S^2_c) is determined
explicitly. This result is used to classify all finite dimensional covariant
first order differential calculi over O_q(S^2_c) for all but exceptional values
of the parameter c.Comment: LaTeX2e, 19 page
