论fsf类与弱拉斯克(weakly Laskerian)类的等价性
On the equivalence of fsf and weakly Laskerian classes
AI总结:
该研究证明诺特环上弱拉斯克模类与FSF模类等价,并据此推导弱拉斯克性质在局部环有限整扩张及完备化张量积下的升降性质,丰富了交换代数中模类的相关理论。
摘要:
本文证明了在诺特环R上,弱拉斯克模类与FSF模类是同一类。利用这一表征,我们证明了弱拉斯克性质可通过局部环同态的有限整扩张下降,且可通过完备化下的张量积上升。
英文摘要:
It is proved that, over a Noetherian ring R, the class of weakly Laskerian and FSF modules are the same classes. By using this characterization we proved that the property of being weakly Laskerian descends by finite integral extensions of local ring homomorphisms and ascends by tensoring under the completion.
