On a Special Class of Non Complete Webs

Julien Sebag (2010)

Annales de la faculté des sciences de Toulouse Mathématiques

In this article, we introduce a special class of non complete webs, the NN-webs. We also study the algebraic and geometric properties of these webs.

On algebraic closures.

R. Raphael (1992)

Publicacions Matemàtiques

This is a description of some different approaches which have been taken to the problem of generalizing the algebraic closure of a field. Work surveyed is by Enoch and Hochster (commutative algebra), Raphael (categories and rings of quotients), Borho (the polynomial approach), and Carson (logic).Later work and applications are given.

On almost discrete space

Ali Akbar Estaji (2008)

Archivum Mathematicum

Let C ( X ) be the ring of real continuous functions on a completely regular Hausdorff space. In this paper an almost discrete space is determined by the algebraic structure of C ( X ) . The intersection of essential weak ideal in C ( X ) is also studied.

On associated and attached prime ideals of certain modules

K. Divaani-Aazar (2001)

Colloquium Mathematicae

Primary and secondary functors have been introduced in [2] and applied to extend some results concerning asymptotic prime ideals. In this paper, the theory of primary and secondary functors is developed and examples of non-exact primary and non-exact secondary functors are presented. Also, as an application, the sets of associated and of attached prime ideals of certain modules are determined.

On Bhargava rings

Mohamed Mahmoud Chems-Eddin, Omar Ouzzaouit, Ali Tamoussit (2023)

Mathematica Bohemica

Let D be an integral domain with the quotient field K , X an indeterminate over K and x an element of D . The Bhargava ring over D at x is defined to be 𝔹 x ( D ) : = { f K [ X ] : for all a D , f ( x X + a ) D [ X ] } . In fact, 𝔹 x ( D ) is a subring of the ring of integer-valued polynomials over D . In this paper, we aim to investigate the behavior of 𝔹 x ( D ) under localization. In particular, we prove that 𝔹 x ( D ) behaves well under localization at prime ideals of D , when D is a locally finite intersection of localizations. We also attempt a classification of integral domains D ...
