诺特PI-代数的可表示性

Representability of Noetherian PI-algebras

Be'eri Greenfeld, Louis Rowen

摘要:

本文讨论Noether PI-代数的可表示性问题。推广了Rowen和Small关于交换诺特环上的每一个有限生成模都是可表示的结果,给出了交换Noetherian PI-代数$R$的可表示机制,其中包括交换子代数$R$(作为模)同构于$R/N$的情形.我们构建了一个家庭的非表示PI-代数证明这些结果的清晰度,以及一些著名的先前的表示结果。

英文摘要:

This note concerns the still open question of representability of Noetherian PI-algebras. Extending a result of Rowen and Small (with an observation of Bergman) that every finitely generated module over a commutative Noetherian ring containing a field is representable, we provide a representability machinery for a Noetherian PI-algebra $R$ containing a field, which includes the case that $R$ is finite (as a module) over a commutative subalgebra isomorphic to $R/N$. We construct a family of non-representable PI-algebras demonstrating the sharpness of these results, as well as of some well known previous representability results.
