Center and derivations of generalized Weyl algebras over $\mathbb{Z}/p^n\mathbb{Z}$

Ruben Mamani-Velasco, Akaki Tikaradze

Let $A$ be either a classical generalized Weyl algebra (also known as a noncommutative deformation of type A Kleinian singularity) or the enveloping algebra $U({\mathfrak{sl}}_2)$…
