Cocycle deformations of Hopf algebras are noncommutative analogues
(in the sense of Connes's noncommutative geometry) of principal fiber
bundles. I will show how to extend the classical theory of polynomial
identities to these objects and how to use these extended identities to
construct versal families of deformations of quantum principal fiber bundles
(joint work with Eli Aljadeff).
