The Gauge Group of a Noncommutative Principal Bundle and Twist Deformations

Paolo Aschieri, Giovanni Landi, Chiara Pagani

We study noncommutative principal bundles (Hopf-Galois extensions) in the context of coquasitriangular Hopf algebras and their monoidal category of comodule algebras. When the tota…
