SK Jain, SR López-Permouth, K Oshiro… - Canadian Journal of …, 1994 - cambridge.org
A module M is said to be weakly N-projective if it has a projective cover π: P (M)↠ M and for
each homomorphism: P (M)→ N there exists an epimorphism σ: P (M)↠ M such that (kerσ) …

[引用][C] Regular endomorphism rings of free modules
RF Shanny - Journal of the London Mathematical Society, 1971 - academic.oup.com
It is well known that if R is a regular ring and F is a free/^-module with finite basis, then
HomR (F, F) is a regular ring ([1]). Skornyakov asks if the condition that F have a finite basis …

Wiles defect for modules and criteria for freeness
Diamond proved a numerical criterion for modules over local rings to be free modules over
complete intersection rings. We formulate a refinement of these results using the notion of …
