Le Matematiche, 2013 In this paper, we utilize the notion of common limit range property in Non-Archimedean Menger PM-spaces and prove some fixed point theorems for two pairs of weakly compatible mappings. Some illustrative examples are furnished to support our results.

A note on the Menger (Rothberger) property and topological games
Topology and its Applications, 2016 Making use of several topological games, a number of conditions either equivalent to or implying either the Menger or Rothberger property are presented. As an example it is shown that a \(T_1\) space \(X\) is Menger (Rothberger) if and only if for each sequence \(\langle\phi_n\rangle\) of neighbourhood assignments for \(X\) and each \(n\) there is a ...

LCAO approximation for scaling properties of the Menger sponge fractal
Optics Express, 2006 The electromagnetic eigenmodes of a three-dimensional fractal called the Menger sponge were analyzed by the LCAO (linear combination of atomic orbitals) approximation and a first-principle calculation based on the FDTD (finite-difference time-domain) method.

A characterization of the Menger property by means of ultrafilter convergence
Topology and its Applications, 2013 We characterize various Menger/Rothberger related properties by means of ultrafilter convergence, and discuss their behavior with respect to products.

ROLE OF MIXED SURFACTANTS ON THE OXIDATION OF MALACHITE GREEN BY NITRITE IONS
Academy Journal of Science and Engineering, 2015 The oxidation of malachite green (MG+) with nitrite ions in aqueous solutions of sodium dodecyl sulphate (SDS), Triton X-100 (TX-100), and their mixtures at 25oC has been used as a probe for investigating the catalytic/inhibitive property of SDS/TX-100 ...

The projective Menger property and an embedding of S into function spaces
Topology and its Applications, 2017 Let \(X\) be a Tychonoff space and \(C_p(X)\) be the space of all real-valued continuous functions on \(X\) with the topology of pointwise convergence. \(X\) is said to be: {\parindent=0.6cm\begin{itemize}\item[--] \textit{Menger} if for every sequence \(\{ \mathcal{U}_n: n \in\mathbb{N}\}\) of open covers of \(X\), there are finite subfamilies ...

Menger-type covering properties of topological spaces
Filomat, 2015 In this paper we find conditions under which the properties of Menger, almost Menger and weakly Menger are equivalent as well as the corresponding properties of Lindel?f-type. We give counterexamples that show the interrelations between those properties.
