Cohen-Macaulay approximations over generically Gorenstein rings

Richard F. Bartels

Let $(R, m)$ be a Cohen-Macaulay local ring with canonical module that is generically Gorenstein. In this paper, I prove isomorphisms relating the minimal MCM approximati…

Cohen-Macaulay approximations and the $SC_{r}$ -condition

Richard F. Bartels

We study the relation between MCM approximations and FID hulls of modules over a Cohen-Macaulay local ring $R$ with canonical module, specifically when $R$ is generically Gorenstei…

Some properties of ideals in Cohen-Macaulay local rings

Richard F. Bartels

For a Cohen-Macaulay local ring $(R, m)$ with canonical module, we study how relations between $index (R)$ and $g ℓℓ (R)$ and between $index (R)$ a…

Generalized Loewy length of Cohen-Macaulay local and graded rings

Richard Bartels

We generalize a theorem of Ding relating the generalized Loewy length $g ℓℓ (R)$ and index of a one-dimensional Cohen-Macaulay local ring $(R, m, k)$ . Ding prov…
