导出函子的上升性质

Ascent properties for derived functors

Sean Sather-Wagstaff

摘要:

给定平坦局部环同态R \to S和两个平坦生成的R-模M和N,我们给出了模Tor^i(M,N)和Ext^i(M,N)具有与其R-模结构相容的S-模结构的条件.

英文摘要:

Given a flat local ring homomorphism R\to S, and two finitely generated R-modules M and N, we describe conditions under which the modules Tor^i(M,N) and Ext^i(M,N) have S-module structures that are compatible with their R-module structures.
