let $r$ be a commutative ring with identity and $mathbb{a}(r)$ be the set of ideals of $r$ with non-zero annihilators. in this paper, we first introduce and investigate the principal ideal subgraph of the annihilating-ideal graph of $r$, denoted by $mathbb{ag}_p(r)$. it is a (undirected) graph with vertices $mathbb{a}_p(r)=mathbb{a}(r)cap mathbb{p}(r)setminus {(0)}$, where $mathbb{p}(r)$ is...
Despite holding that all concepts are strictly speaking innate, Leibniz attempts to accommodate the common belief that at least some concepts are adventitious by appealing to his theory of ideal action. The essential idea is that an innate concept can be considered adventitious, in a sense, just in case its ideal cause is to be found outside the mind of the one who possesses the concept. I expl...
in this paper we define the notions of ultra and involution ideals in bck-algebras. then we get the relation among them and other ideals as (positive) implicative, associative, commutative and prime ideals. specially, we show that in a bounded implicative bck-algebra, any involution ideal is a positive implicative ideal and in a bounded positive implicative lower bck-semilattice, the notions of...
Let G be the Sylow 2-subgroup of the unitary group SU 3(4). We find two essential classes in the mod 2 cohomology ring of G whose product is nonzero. In fact, the product is the “last survivor” of Benson–Carlson duality. Recent work of Pakianathan and Yalçın then implies a result about connected graphs with an action of G. Also, there exist essential classes which cannot be written as sums of t...
H ealth education is a critical "therapeutic strategy" in asthma management.' Various teaching tools and educational programs play distinct roles in education. Table 1 outlines some educational tools on asthma. A program is a package of services or information intended to produce particular results (Table 2). Specific and clear goals, combined with appropriate methods for reaching the goals, ar...
let $s$ be an ordered semigroup. a fuzzy subset of $s$ is anarbitrary mapping from $s$ into $[0,1]$, where $[0,1]$ is theusual interval of real numbers. in this paper, the concept of fuzzygeneralized bi-ideals of an ordered semigroup $s$ is introduced.regular ordered semigroups are characterized by means of fuzzy leftideals, fuzzy right ideals and fuzzy (generalized) bi-ideals.finally, two m...
