Drinfeld-Xu bialgebroid 2-cocycles twist the antipode
Zoran Škoda
Ping Xu generalized Drinfeld 2-cocycles from bialgebras to associative bialgebroids over noncommutative base algebras. Any counital Drinfeld--Xu 2-cocycle twists the base algebra o…
Examples of scalar extension Hopf algebroids over a universal enveloping algebra
Martina Stojić, Zoran Škoda
We present several related examples of Hopf algebroids over a universal enveloping algebra which are of the scalar extension Hopf algebroid type and explain their origin in Lie and…
A note on symmetric orderings
Zoran Škoda
Let be the completion by the degree of a differential operator of the -th Weyl algebra with generators . Consider el…
Compatibility of (co)actions and localizations
Zoran Škoda
Earlier, Lunts and Rosenberg studied a notion of compatibility of endofunctors with localization functors, with an application to the study of differential operators on noncommutat…
Quantum heaps, cops and heapy categories
Zoran Škoda
A heap is a structure with a ternary operation which is intuitively a group with forgotten unit element. Quantum heaps are associative algebras with a ternary cooperation which are…
Every quantum minor generates an Ore set
Zoran Škoda
The subset multiplicatively generated by any given set of quantum minors and the unit element in the quantum matrix bialgebra satisfies the left and right Ore conditions.
