An Atiyah Sequence for Noncommutative Principal Bundles
arXiv:2107.04653 · doi:10.3842/SIGMA.2022.015
Abstract
We present a derivation-based Atiyah sequence for noncommutative principal bundles. Along the way we treat the problem of deciding when a given -automorphism on the quantum base space lifts to a -automorphism on the quantum total space that commutes with the underlying structure group.
