单模的同调维数

程福长 - 广西师范大学学报: 自然科学版, 1994 - cqvip.com
徐金中证明了交换环上单模是内射的当且仅当它为平坦的. 姚慕生证明一个一般的结论:
交换环上任一单模的平坦维数等于它的内射维数. 利用H. Cartan 给出的著名公式, 证明了当R/I …

Dual modules, f-projective modules and Π-coherence over trivial ring extensions

L Mao - Communications in Algebra, 2024 - Taylor & Francis
Abstract Let R⋉ M be a trivial extension of a ring R by an RR-bimodule M. We first describe
explicitly the structure of a dual module over R⋉ M. Then we characterize Mittag-Leffler …
