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…
Why blockchain and smart contracts need semantic descriptions
Zoran Škoda
We argue that there is a hierarchy of levels describing to that particular level relevant features of reality behind the content and behavior of blockchain and smart contracts in t…
On interpolations between Jordanian twists
Daniel Meljanac, Stjepan Meljanac, Zoran Škoda +1
We consider two families of Drinfeld twists generated from a simple Jordanian twist further twisted with 1-cochains. Using combinatorial identities, they are presented as a series…
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…
Čech cocycles for quantum principal bundles
Zoran Škoda
In other to study connections and gauge theories on noncommutative spaces it is useful to use the local trivializations of principal bundles. In this note we show how to use noncom…
