On the definability of Menger spaces which are not σ-compact

open access: yesTopology and its Applications, 2017
Hurewicz proved completely metrizable Menger spaces are a-compact. We extend this to Oech-complete Menger spaces, and consistently, to projective metrizable Menger 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.

Results on Expansion Maps in Fuzzy Menger Space via Property-(E.A) and (E.A)-like Property [PDF]

open access: yesRatio Mathematica
The main goal of this paper is to establish two results in fuzzy menger space by using property-(E.A), (E.A) like property and occasionally weakly compatible mappings.

On nearly Menger and nearly star-Menger spaces [PDF]

open access: yesFilomat, 2019
In 1999, Kocinac defined and characterized the almost Menger property. Following this concept, we define and investigate nearly Menger and nearly star-Menger spaces. Every Menger space is nearly Menger, and every nearly Menger space is almost Menger. It is demonstrated that a nearly Menger space may not necessarily be a Menger space. In the

Common fixed point theorem for occasionally weakly compatible mappings in Menger space [PDF]

open access: yesSurveys in Mathematics and its Applications, 2011
The concept of occasionally weakly compatible (shortly, owc) mappings introduced by Al-Thagafi and Shahzad [2], which is more general than the concept of weakly compatible maps.

Pair (F, h) upper class on some fixed point results in probabilistic Menger space

open access: yesInternational Journal of Analysis and Applications, 2020
In this paper, we define the concept of (F, h, α, β, ψ)- contractive mappings in a probabilistic Menger space, which generalizes some previous related concepts. Also, we investigate the existence of fixed points for such mappings. Some examples are given

Nearly Soft Menger Spaces [PDF]

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.

Menger spaces and inverse limits [PDF]

open access: yesPacific Journal of Mathematics, 1988
In 1984, M. Bestvina characterized the Menger universal n-dimensional spaces. This characterization is used by the authors to identify certain inverse sequences having inverse limit homeomorphic to one of the Menger spaces. Specific models of Menger spaces are then constructed in the Hilbert cube as inverse limits of polyhedra.
