LCAO approximation for scaling properties of the Menger sponge fractal
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.

Menger-type covering properties of topological spaces
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.

The projective Menger property and an embedding of S into function spaces
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 ...

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

On metric spaces with the Haver property which are Menger spaces
The aim of this paper is to construct topological spaces with some special properties under Martin's axiom (MA) answering some questions by \textit{L. Babinkostova} [Topology Appl. 154, No.~9, 1971--1979 (2007; Zbl 1128.54014) and ibid. 156, No.~1, 2--9 (2008; Zbl 1157.54010)]. The results: under MA, there is a separable metric space \((V,d)\) with the

Almost strongly star-Menger and related properties
In this paper we introduce the almost strongly star-Menger property and we provide some results and relationships with another known properties in literature. Furthermore, we characterize the almost strongly star-Menger and the almost star-Menger properties in hyperspaces endowed with the hit-and-miss topology $\tau_\Delta$, by using two new selection ...
