Title: Nichols Algebras and Quantum Principal Bundles,
Abstract: A general procedure for constructing Yetter-Drinfeld modules from quantum
principal bundles is introduced. As an application a Yetter-Drinfeld structure
is put on the cotangent space of the Heckenberger-Kolb calculi of the quantum
Grassmannians. For the special case of quantum projective space the associated
braiding is shown to be non-diagonal and of Hecke type. Moreover, its Nichols
algebra is shown to be finite-dimensional and equal to the anti-holomorphic
part of the total differential calculus.
