Comparisons Between Annihilators of Tor and Ext
Souvik Dey , Ryo Takahashipp. 123-139
Abstract
In this paper, we compare annihilators of Tor and Ext modules of finitely generated modules over a commutative noetherian ring. For local Cohen–Macaulay rings, one of our results refines a theorem of Dao and Takahashi.
