The Role of the Canonical Element in the Quantized Algebra of Differential Operators $\A\rtimes\U$

Chryssomalis Chryssomalakos, Peter Schupp, Paul Watts

We review the construction of the cross product algebra $\A\rtimes\U$ from two dually paired Hopf algebras $\U$ and $\A$. The canonical element in $\U \otimes \A$ is then introduce…
