It is shown that every quantum principal bundle with a compact structure group is a Hopf-Galois extension. This property naturally extends to the level of general differential structures, so that every differential calculus over a quantum principal bundle with a compact structure group is a graded-differential variant of the Hopf-Galois extension.

  1. Categorified structures over moduli spaces: Anomalies, non-invertible symmetries, and exceptional holonomy

    hep-th 2025-06 conditional novelty 7.0 of 10

    The paper conjectures that non-invertible Ising and tricritical Ising symmetries organize closed string states and D-brane categories into categorical bundles over moduli spaces of exceptional holonomy compactifications.

  2. Gauge transformations on quantum principal bundles

    math.QA 2025-05 conditional novelty 4.0 of 10

    Gauge transformations on quantum principal bundles are extended to differential forms, giving an action on connections and curvature, with the noncommutative 2-torus as the main new example.
