Integral closures of ideals in the Rees ring

Y. Tiraş (1993)

Colloquium Mathematicae

Similarity:

The important ideas of reduction and integral closure of an ideal in a commutative Noetherian ring A (with identity) were introduced by Northcott and Rees [4]; a brief and direct approach to their theory is given in [6, (1.1)]. We begin by briefly summarizing some of the main aspects.

An overview of some recent developments on integer-valued polynomials: Answers and Questions

Jean-Luc Chabert (2010)

Actes des rencontres du CIRM

Similarity:

The purpose of my talk is to give an overview of some more or less recent developments on integer-valued polynomials and, doing so, to emphasize that integer-valued polynomials really occur in different areas: combinatorics, arithmetic, number theory, commutative and non-commutative algebra, topology, ultrametric analysis, and dynamics. I will show that several answers were given to open problems, and I will raise also some new questions.

Zero-divisors of content algebras

Peyman Nasehpour (2010)

Archivum Mathematicum

Similarity:

In this article, we prove that in content extentions minimal primes extend to minimal primes and discuss zero-divisors of a content algebra over a ring who has Property (A) or whose set of zero-divisors is a finite union of prime ideals. We also examine the preservation of diameter of zero-divisor graph under content extensions.
