Proposition 0.1. Let R be a commutative ring. TFAE: 1. Every ideal in R is finitely generated. 2. Every chain of ideals I1 ⊆ I2 ⊆ · · · is stable. That is, there exists n such that In = In+1 = · · · . 3. Every nonempty set of ideals has a maximal element wrt inclusion. Proof. 1. (1) =⇒ (2). I = ⋃ k Ik ideal in R. I is generated by x1, x2, . . . xm. There exists n such that x1, . . . , xm ∈ In. ...

In this paper, we study MV?algebra of continuous functions C(X) and maximal ideals C(X). Furthermore, Z?ideal Z??ideal are introduced proved that every in is a but the converse not true finitely generated basic Z??ideal. Also, investigate meet join two Z?ideals (Z??ideal) Complemented elements examined their properties have been studied. particular, relationship between ideal by them (Z??ideals...

In this paper, we define the notion of minimal prime ideals hoops and investigate some properties them. Then by using annihilators, study relation between annihilators. Also, introduce zero divisors elements prove that set all is a union hoop. Finally, notions maximal hoop, two new as p-ideal m-ideal. them every semi-simple hoop an m-ideal it.

Data used in machine learning applications is prone to contain both vague and incomplete information. Many authors have proposed to use fuzzy rough set theory in the development of new techniques tackling these characteristics. Fuzzy sets deal with vague data, while rough sets allow to model incomplete information. As such, the hybrid setting of the two paradigms is an ideal candidate tool to c...

We study non-holonomic overideals of a (left) differential ideal J ⊂ F [dx, dy ] in two variables where F is a differentially closed field of characteristic zero. The main result states that a principal ideal J = 〈P 〉 generated by an operator P with a separable symbol symb(P ) (being a homogeneous polynomial in two variables) has a finite number of maximal non-holonomic overideals. This stateme...

Fuzzy Logic has been successfully applied to all kinds of scenarios, where degrees of membership and truth can be systematically discerned. However it is highly contentious whether this fact renders Fuzzy Logic an ideal tool for modelling reasoning with vague concepts and propositions. There is a lively and prolific debate in analytic philosophy about so-called theories of vagueness. Interestin...

A finitely generated $R$-module is said to be a module of type ($F_r$) if its $(r-1)$-th Fitting ideal is the zero ideal and its $r$-th Fitting ideal is a regular ideal. Let $R$ be a commutative ring and $N$ be a submodule of  $R^n$ which is generated by columns of  a matrix $A=(a_{ij})$ with $a_{ij}in R$ for all $1leq ileq n$, $jin Lambda$, where $Lambda $ is a (possibly infinite) index set.  ...
