Derivations with Quantum Group Action
Ulrich Hermisson
The derivations of a left coideal subalgebra B of a Hopf algebra A which are compatible with the comultiplication of A (that is, the covariant first order differential calculi, as…

Construction of Covariant Differential Calculi on Quantum Homogeneous Spaces
Ulrich Hermisson
A method of constructing covariant differential calculi on a quantum homogeneous space is devised. The function algebra X of the quantum homogeneous space is assumed to be a left c…
