5. Etingof’s Problem


    1. Add remark

      Problem 5.1.

      [Toby Stafford] Let $A$ be a filtered deformation of a commutative finitely generated domain $A_0$, where $A_0$ is a $k$-algebra and $\text{char } k = p$. Is $A$ PI?
        1. Remark. [Toby Stafford] This is true for enveloping algebras and rings of differential operators.
