A produção científica em empresas familiares: um enfoque conceitual

open access: yesRevista de Administração Pública, 2011
Uma das principais dificuldades para a compreensão das pesquisas em empresas familiares é a ausência de consenso sobre uma definição stricto sensu, sendo as existentes baseadas em diferentes perspectivas e critérios.

Prime ideal on the end_Z (Z^n ) Ring

open access: yesAl-Jabar, 2022
The set of all endomorphisms over -module  is a non-empty set denoted by . From  we can construct the ring of  over addition and composition function. The prime ideal is an ideal which satisfies the properties like the prime numbers.

Multiplier ideals of monomial ideals [PDF]

open access: yesTransactions of the American Mathematical Society, 2001
In this note we discuss a simple algebraic calculation of the multiplier ideal associated to a monomial ideal in affine n n -space. We indicate how this result allows one to compute not only the multiplier ideal but also the log canonical threshold of an ideal in terms of its Newton polygon.

On Structure of Infinite B*-Matrices over Normed Fields

open access: yesInventions, 2021
This article is devoted to the investigation of infinite B*-matrices and linear operators over normed fields. Their structure is studied in the paper. Ideals and centers of the corresponding to them B*-algebras are scrutinized.

THE IDEALS OF AN IDEAL EXTENSION [PDF]

open access: yesJournal of Algebra and Its Applications, 2010
Given two unital associative rings R ⊆ S, the ring S is said to be an ideal (or Dorroh) extension of R if S = R ⊕ I, for some ideal I ⊆ S. In this note, we investigate the ideal structure of an arbitrary ideal extension of an arbitrary ring R. In particular, we describe the Jacobson and upper nil radicals of such a ring, in terms of the Jacobson and ...

Connectedness modulo an ideal [PDF]

open access: yes, 2016
For a topological space $X$ and an ideal $\mathscr{H}$ of subsets of $X$ we introduce the notion of connectedness modulo $\mathscr{H}$. This notion of connectedness naturally generalizes the notion of connectedness in its usual sense. In the case when $X$

Some Examples of BL-Algebras Using Commutative Rings

open access: yesMathematics, 2022
BL-algebras are algebraic structures corresponding to Hajek’s basic fuzzy logic. The aim of this paper is to analyze the structure of BL-algebras using commutative rings. Due to computational considerations, we are interested in the finite case.

Permanental Ideals

open access: yesJournal of Symbolic Computation, 2000
The principal result is a primary decomposition of ideals generated by the (2x2)-subpermanents of a generic matrix. These permanental ideals almost always have embedded components and their minimal primes are of three distinct heights. Thus the permanental ideals are almost never Cohen-Macaulay, in contrast with determinantal ideals.
