DERIVATIONS WITH QUANTUM GROUP ACTION
DERIVATIONS WITH QUANTUM GROUP ACTION
ABSTRACT 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 defined by Woronowicz, on a quantum homogeneous space) are related to certain right ideals of ℬ. The correspondence is …
