关于满足多项式恒等式的q-斜迭代Ore扩张

On q-skew Iterated Ore Extensions Satisfying a Polynomial Identity

André Leroy, Jerzy Matczuk

摘要:

对于满足多项式恒等式的迭代Ore扩张,我们提出了一种擦除导子的基本方法。因此,我们恢复了Haynal在“q-斜多项式环中的PI度奇偶性”(J. Algebra 319,2008,4199-4221)中获得的一些结果。我们还证明,在温和的假设下,$R_n=R[x_1;\si_1,\de_1]...[x_n;\si_n;\de_n]$的Ore扩张$R[x_1;\si_1]...[x_n;\si_n]$存在,是PI,如果$R_n$是PI。

英文摘要:

For iterated Ore extensions satisfying a polynomial identity we present an elementary way of erasing derivations. As a consequence we recover some results obtained by Haynal in "PI degree parity in q-skew polynomial rings" (J. Algebra 319, 2008, 4199-4221). We also prove, under mild assumptions on $R_n=R[x_1;\si_1,\de_1]...[x_n;\si_n;\de_n]$ that the Ore extension $R[x_1;\si_1]...[x_n;\si_n]$ exists and is PI if $R_n$ is PI.
