Abstract:
For any preassigned integer $n \geq 3$, a Noetherian affine PI ring $R$ is constructed with $\operatorname {gl dim }R \leq 3$, but $\operatorname {gl dim}\left ( {R/N\left ( R \right )} \right ) = n$. A second similar ring is constructed with $\operatorname {gl dim }R \leq 5$ and $\operatorname {gl dim}\left ( {R/N\left ( R \right )} \right ) = \infty$.References
