Nearly Soft Menger Spaces

open access: yesJournal of Mathematics, 2020
In this paper, we define a weak type of soft Menger spaces, namely, nearly soft Menger spaces. We give their complete description using soft s-regular open covers and prove that they coincide with soft Menger spaces in the class of soft regular⋆ spaces ...

About uniformly Menger spaces [PDF]

open access: yesMathematica Moravica
Precompact type properties - precompactness (=totally precompactness), s-precompactness, pre-Lindelöfness, (=ℵ0-boundedness), t -boundedness - belong to the basic important invariants studied in the uniform topology.

Weakly strongly star-Menger spaces

open access: yesCubo, 2021
A space $X$ is called weakly strongly star-Menger space if for each sequence ($\mathcal{U}_{n} : n \in \omega$) of open covers of $X,$ there is a sequence $(F_n : n\in\omega)$ of finite subsets of $X$ such that $\overline{\bigcup_{n\in\omega} St(F_n ...

Selection principles and covering properties in bitopological spaces

open access: yesApplied General Topology, 2020
Our main focus in this paper is to introduce and study various selection principles in bitopological spaces. In particular, Menger type, and Hurewicz type covering properties like: Almost p-Menger, star p-Menger, strongly star p-Menger, weakly p-Hurewicz,

Cayley-Menger coordinates. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1986
A major obstacle in applying distance geometry techniques is the analytical complexity of the Cayley-Menger determinants that are used to characterize euclidian spaces in terms of distances between points. In this paper we show that, with the aid of a theorem of Jacobi, the complex Cayley-Menger determinants can be replaced by simpler determinants, and

Superelastic behaviors of additively manufactured porous NiTi shape memory alloys designed with Menger sponge-like fractal structures

open access: yesMaterials & Design, 2021
Additively manufactured porous NiTi alloys hold unprecedented promise in metallic implants due to their low elastic modulus and superelastic behavior. Such porous structures are usually topologically ordered and designed with periodically-repeating unit ...

Menger vs. Smith: Menger Reader of Smith

open access: yesJournal of Contextual Economics – Schmollers Jahrbuch, 2023
Based on some of Carl Menger’s publications, his estate and archives, this paper asks how the Austrian School relates to the thought of Adam Smith. Was Menger a heir of Smith, as Gustav Schmoller, leader of the German Historical School and Menger’s arch-enemy, insinuated?
