en pedagogic, le souci d'cvaluer correctcment les formes a fait l'objet des debats tres anciens. les contestations vivcs se poursuivent encore 3 cause de )'importance du sujet. l'evaluation permct au professeur de contrdler et de detectcr les eventuelles insuffisances de son enseignement. des notes precises soot donnees a partir des criteres. l'cvaluation se sert des pr...

Let (R, m) be a complete local domain containing the rationals. Then there exists an integer l such that for any ideal I ⊆ R, if f ∈ m, f / ∈ In, then there exists a derivation δ of R with δ(f) / ∈ In+l. This note grew out of a question raised by C. Huneke some years ago: Suppose (R, m) is a complete local domain with perfect residue class field k which it contains. Call an element x ∈ R deriva...

For Banach algebras A in a class which includes all group and function algebras, we show that the family of ideals of A with the same hull is typically quite large, containing ascending and descending chains of arbitrary length through any ideal in the family, and that typically a closed ideal of A whose hull meets the Silov boundary of A cannot be countably generated algebraically. Guided by t...

notions of strongly regular, regular and left(right) regular $gamma$−semigroupsare introduced. equivalent conditions are obtained through fuzzy notion for a$gamma$−semigroup to be either strongly regular or regular or left regular.

We show for 2 p < 1 and subspaces X of quotients of L p with a 1-unconditional nite-dimensional Schauder decomposition that K (X; ` p) is an M-ideal in L(X; ` p).

Yemlik kolza için ideal ekim normunun belirlenmesi amacıyla bu çalışma yürütülmüştür. Çalışmada dekara 400 g, 800 1200 1600 2000 g ve 2400 olmak üzere altı normu kullanılmıştır. Ekimler 02 Ekim 2020 tarihinde, hasatlar ise 29 Nisan 2021 tarihinde yapılmıştır. farklı normlarının bitki boyu, yeşil ot verimi, kuru ham protein, ADF, NDF sindirilebilir madde oranları, nispi yem değeri, kalsiyum, mag...

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...

We computationally verify that certain group ring elements obtained from the first derivatives of abelian L-functions at the origin annihilate ideal class groups. In our test cases, these ideal class groups are connected with cyclic extensions of degree 6 over real quadratic fields.
