For estimating the population variance S y of study variable y, a class of chain estimators of S y has been proposed in the presence of two auxiliary variables x and z by using known information on population mean and variance of the second auxiliary variable z. In this proposed class, the second auxiliary variable z is directly highly correlated with the first auxiliary variable x, whereas the...

Lemma 1.2. Suppose the linear third-order differential equation z′′′ p t z 0, t ∈ I 1.9 has an eventually positive increasing solution on...

in this paper, we introduce a method by which we can find a close connection between the set of prime $z$-ideals of $c(x)$ and the same of $c(y)$, for some special subset $y$ of $x$. for instance, if $y=coz(f)$ for some $fin c(x)$, then there exists a one-to-one correspondence between the set of prime $z$-ideals of $c(y)$ and the set of prime $z$-ideals of $c(x)$ not containing $f$. moreover, c...
and Applied Analysis 3 x ∈ X i.e., cl Oa x Oa x for all x ∈ X . Then, ω ∈ Oa z for all z ∈ C. Since x ∈ C, then ω ∈ Oa x . On the other hand, since x ∈ x ⊂ C ⊂ Oa ω , then ω ∈ x . Hence, C x . In the following lemma, we give necessary and sufficient conditions for the equivalence classes to be S-invariant classes. Lemma 2.2. Let S,X, a be an S-flow. A class x ∈ X is an S-invariant class if and ...
The papers [23], [24], [4], [5], [2], [20], [21], [9], [1], [22], [13], [15], [16], [12], [10], [11], [17], [14], [25], [3], [7], [6], [19], and [8] provide the notation and terminology for this paper. For simplicity, we adopt the following convention: X denotes a complex Banach algebra, w, z, z1, z2 denote elements of X, k, l, m, n denote natural numbers, s1, s2, s3, s, s ′ denote sequences of...
We say that a 〈∨, 0〉-semilattice S is conditionally co-Brouwerian, if (1) for all nonempty subsets X and Y of S such that X ≤ Y (i.e., x ≤ y for all 〈x, y〉 ∈ X × Y ), there exists z ∈ S such that X ≤ z ≤ Y , and (2) for every subset Z of S and all a, b ∈ S, if a ≤ b ∨ z for all z ∈ Z, then there exists c ∈ S such that a ≤ b ∨ c and c ≤ Z. By restricting this definition to subsets X , Y , and Z ...
The terminology and notation used in this paper have been introduced in the following articles: [16], [3], [19], [5], [4], [1], [15], [6], [17], [18], [9], [8], [2], [20], [12], [14], [10], [13], [7], and [11]. For simplicity, we adopt the following rules: S, T denote non trivial real normed spaces, x0 denotes a point of S, f denotes a partial function from S to T , h denotes a convergent to 0 ...
