Algebraic geometry of Hopf-Galois extensions
arXiv:q-alg/9707022
Abstract
We continue the study of Hopf-Galois extensions with central invariants for a finite dimensional Hopf algebra. We concentrate on the geometrical side on the subject. We understand how to localize Hopf-Galois extensions and to paste them from local datum.
