Covariant first order differential calculus on quantum Euclidean spheres
Martin Welk
We study covariant differential calculus on the quantum spheres S_q^{N-1} which are quantum homogeneous spaces with coactions of the quantum groups O_q(N). The first part of the pa…

Covariant first order differential calculus on quantum projective spaces
Martin Welk
We investigate covariant first order differential calculi on the quantum complex projective spaces CP_q^{N-1} which are quantum homogeneous spaces for the quantum group SU_q(N). He…

Differential Calculus on Quantum Spheres
Martin Welk
We study covariant differential calculus on the quantum spheres S_q^2N-1. Two classification results for covariant first order differential calculi are proved. As an important step…
