✦ Synopsis


On dit qu'une partie d'un anneau intègre est pleine si les polynômes à valeurs entières sur cette partie le sont aussi sur ranneau tout entier. On montre que, sur un anneau noethérien de dimension 1 , à corps résiduels finis et localement analytiquement irréductible, les parties pleines sont les parties localement denses (pour les topologies (\mathfrak{p})-adiques). Les parties pleines déterminent également la propriété de Skolem forte. 1993 Academic Press, Inc.

A full subset of a domain is a subset such that integral-valued polynomials on this subset are integral-valued on the whole domain. If (A) is a one-dimensional locally analytically irreducible domain with finite residue fields, it is shown that a subset (E) of (A) is full if and only if it is locally dense (for the (\mathfrak{p})-adic topologies). Full subsets determine also the strong Skolem property. O 1993 Academic Press. Inc.

A module M is known to be a CS-module or an extending module if every Ž . complement submodule of M is a direct summand. It is shown that i a simple ring R must be right noetherian if every cyclic singular right R-module is CS, and Ž . ii over a simple ring R if every proper cyclic right module is

New Invariants of Noetherian Local Rings
✍ Jee Koh; Kisuk Lee 📂 Article 📅 2001 🏛 Elsevier Science 🌐 English ⚖ 158 KB

We investigate properties of certain invariants of Noetherian local rings, including their behavior under flat local homomorphisms. We show that these invariants are bounded by the multiplicity for Cohen-Macaulay local rings with infinite residue fields, and they all agree with the multiplicity when
