Lazy cohomology: an analogue of the Schur multiplier for arbitrary Hopf algebras

Julien Bichon, Giovanna Carnovale

We propose a detailed systematic study of a group H^2_L(A) associated, by elementary means of lazy 2-cocycles, to any Hopf algebra A. This group was introduced by Schauenburg (with…

Spherical orbits and representations of $U_{ε} (g)$

Nicoletta Cantarini, Giovanna Carnovale, Mauro Costantini

Let $U_{ε} (g)$ be the simply connected quantized enveloping algebra associated to a finite-dimensional complex simple Lie algebra $g$ at the roots of unity. The D…

On the braided Fourier transform in the n-dimensional quantum space

Giovanna Carnovale

We work out a theory of integrability on the braided covector Hopf algebra and braided vector Hopf algebra of type A_n as introduced by Kempf and Majid. Starting by their definitio…
