Resumen
We review Hopf–Galois extensions, in particular faithfully flat ones, accepted to be
the noncommutative algebraic dual of a principal bundle. We also make a short digression
into how quantum groups relate to Hopf—Galois extensions. Several examples are given,
in order to provide a satisfactory understanding of each topic.
