A note on k-c-semistratifiable spaces and strong $β$ -spaces

Li-Xia Wang, Liang-Xue Peng (2011)

Mathematica Bohemica

Similarity:

Recall that a space $X$ is a c-semistratifiable (CSS) space, if the compact sets of $X$ are $G_{δ}$ -sets in a uniform way. In this note, we introduce another class of spaces, denoting it by k-c-semistratifiable (k-CSS), which generalizes the concept of c-semistratifiable. We discuss some properties of k-c-semistratifiable spaces. We prove that a $T_{2}$ -space $X$ is a k-c-semistratifiable space if and only if $X$ has a $g$ function which satisfies the following conditions: (1) For each $x \in X$ , ${x} = ⋂ {g (x, n) : n \in ℕ}$ and $g (x, n + 1) \subseteq g (x, n)$ for each...

Necessary and sufficient conditions for oscillations of delay partial difference equations

Bing Gen Zhang, Shu Tang Liu (1995)

Discussiones Mathematicae, Differential Inclusions, Control and Optimization

Similarity:

This paper is concerned with the delay partial difference equation (1) $A_{m + 1, n} + A_{m, n + 1} - A_{m, n} + Σ_{i = 1}^{u} p_{i} A_{m - k_{i}, n - l_{i}} = 0$ where $p_{i}$ are real numbers, $k_{i}$ and $l_{i}$ are nonnegative integers, u is a positive integer. Sufficient and necessary conditions for all solutions of (1) to be oscillatory are obtained.

Boundedness of Third-order Delay Differential Equations in which $h$ is not necessarily Differentiable

Mathew O. Omeike (2015)

Acta Universitatis Palackianae Olomucensis. Facultas Rerum Naturalium. Mathematica

Similarity:

In this paper we study the boundedness of solutions of some third-order delay differential equation in which $h (x)$ is not necessarily differentiable but satisfy a Routh–Hurwitz condition in a closed interval $[δ, k a b] \subset (0, a b)$ .

Delay-dependent stability conditions for fundamental characteristic functions

Hideaki Matsunaga (2023)

Archivum Mathematicum

Similarity:

This paper is devoted to the investigation on the stability for two characteristic functions $f_{1} (z) = z^{2} + p e^{- z τ} + q$ and $f_{2} (z) = z^{2} + p z e^{- z τ} + q$ , where $p$ and $q$ are real numbers and $τ > 0$ . The obtained theorems describe the explicit stability dependence on the changing delay $τ$ . Our results are applied to some special cases of a linear differential system with delay in the diagonal terms and delay-dependent stability conditions are obtained.

On the Cauchy problem in linear viscoelasticity

Pasquale Renno (1983)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

Similarity:

Con riferimento all’operatore integrodifferenziale della viscoelasticità lineare nella formulazione creep, si determina la soluzione fondamentale $E$ in corrispondenza di un’arbitraria funzione di memoria. Di conseguenza viene risolto esplicitamente il problema di Cauchy relativo al moto unidimensionale di un sistema viscoelastico $\mathcal{B}$ , omogeneo ed isotropo, determinato da dati iniziali e storia di stress comunque prefissati. Successivamente, nell’ambito di opportune ipotesi di memoria labile,...

Bond ionization energies: thiophosphoryl compounds

Marco V. Andreocci, Carla Cauletti, Claudio Furlani (1977)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

Similarity:

Negli spettri fotoelettronici (p.e.) indotti da radiazione ultra-violetta di serie omologhe di composti, si trovano bande in ben definite regioni di energia, che possono essere assegnate empiricamente a ionizzazione di legami specifici o di coppie solitarie di elettroni. L’effetto dell'intorno chimico sulle energie di ionizzazione si esplica in piccoli spostamenti, che hanno una dipendenza approssimativamente lineare dall'ettronegatività di atomi o gruppi vicini. La discussione riguarda...

Explicit form for the discrete logarithm over the field $GF (p, k)$

Gerasimos C. Meletiou (1993)

Archivum Mathematicum

Similarity:

For $a$ generator of the multiplicative group of the field $G F (p, k)$ , the discrete logarithm of an element $b$ of the field to the base $a$ , $b \neq 0$ is that integer $z : 1 \leq z \leq p^{k} - 1$ , $b = a^{z}$ . The $p$ -ary digits which represent $z$ can be described with extremely simple polynomial forms.
