Galois Corings and a Jacobson-Bourbaki type Correspondence

J. Cuadra, J. Gomez-Torrecillas

The Jacobson-Bourbaki Theorem for division rings was formulated in terms of corings by Sweedler in 1975. Finiteness conditions hypotheses are not required in this new approach. In…

Extending lazy 2-cocycles on Hopf algebras and lifting projective representations afforded by them

Juan Cuadra, Florin Panaite

We study some problems related to lazy 2-cocycles, such as: extension of (lazy) 2-cocycles to a Drinfeld double and to a Radford biproduct, Yetter-Drinfeld data obtained from lazy…

Cocycle twisting of E(n)-module algebras and applications to the Brauer group

G. Carnovale, J. Cuadra

We classify the orbits of coquasi-triangular structures for the Hopf algebra E(n) under the action of lazy cocycles and the Hopf automorphism group. This is applied to detect subgr…
