On the geometry of quantum spheres and hyperboloids

Giovanni Landi, Chiara Pagani

We study two classes of quantum spheres and hyperboloids which are -quantum spaces for the quantum orthogonal group . We construct line bundles over the qu…

Atiyah sequences of braided Lie algebras and their splittings

Paolo Aschieri, Giovanni Landi, Chiara Pagani

Associated with an equivariant noncommutative principal bundle we give an Atiyah sequence of braided derivations whose splittings give connections on the bundle. Vertical braided d…

Braided Hopf algebras and gauge transformations II: -structures and examples

Paolo Aschieri, Giovanni Landi, Chiara Pagani

We consider noncommutative principal bundles which are equivariant under a triangular Hopf algebra. We present explicit examples of infinite dimensional braided Lie and Hopf algebr…

Braided Hopf algebras and gauge transformations

Paolo Aschieri, Giovanni Landi, Chiara Pagani

We study infinitesimal gauge transformations of an equivariant noncommutative principal bundle as a braided Lie algebra of derivations. For this, we analyse general -braided Hop…

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…

A class of differential quadratic algebras and their symmetries

Giovanni Landi, Chiara Pagani

We study a multi-parametric family of quadratic algebras in four generators, which includes coordinate algebras of noncommutative four-planes and, as quotient algebras, noncommutat…
