Some fixed point theorems for contractive multivalued mappings in Menger probabilistic metric like spaces

open access: yesپژوهش‌های ریاضی, 2021
In this paper,  first by using the constructions of probabilistic b-metric Menger space and probabilistic metric like Menger space,  we introduce probabilistic b-metric like Menger space and present some examples of it.

Mises e Hayek Desomogeneizados

open access: yesMises, 2014
Desde seu renascimento no início dos anos 1970, o que veio a se chamar de “Economia Austríaca” tem sido considerado, pela maior parte de seus adeptos contemporâneos, como a continuação de uma tradição unificada que pode ser rastreada até Carl Menger ...

On traditional Menger and Rothberger variations

open access: yesApplied General Topology
We present a comprehensive report on the relationships between variations of the Menger and Rothberger selection properties with respect to w-covers and k-covers in the most general topological setting and address the finite productivity of some of these

The Hausdorff–Pompeiu Distance in Gn-Menger Fractal Spaces

open access: yesMathematics, 2022
This paper introduces a complete Gn-Menger space and defines the Hausdorff–Pompeiu distance in the space. Furthermore, we show a novel fixed-point theorem for Gn-Menger-θ-contractions in fractal spaces.

Mises’ Incomplete Theory of the Value of Money

open access: yesTheory, Methodology, Practice, 2017
Ludwig von Mises introduced the concept of marginal utility into Austrian economics. He presented what he described as a complete theory of the value of money on the basis of the subjective theory of value and its peculiar doctrine of marginal utility ...

Economia como Ciência Teórica e suas Relações com as Ciências Econômicas Históricas e Práticas – Parte 3

open access: yesMises, 2014
Neste texto Menger continua sua crítica às teses metodológicas da Escola Histórica Alemã. Para Menger, toda abordagem teórica exata seria parcial, mesmo nas ciêncais físicas, o que torna impossível a pretensão holística dos alemães.

Fixed point theorem by using ψ–contraction and (ϕ,φ)–contraction in probabilistic 2–metric spaces

open access: yesAlexandria Engineering Journal, 2020
This research paper investigates and proves some theorems of the fixed point for self–mapping [T:X→X] under (ϕ,ψ)–contractive mappings and (ϕ,φ)–contractive mappings in Menger probabilistic 2–metric space.

A non-discrete space X with Cp(X) Menger at infinity

open access: yesApplied General Topology, 2019
In a paper by Bella, Tokgös and Zdomskyy it is asked whether there exists a Tychonoff space X such that the remainder of Cp(X) in some compactification is Menger but not σ-compact.

Selection principles: s-Menger and s-Rothberger-bounded groups

open access: yesApplied General Topology, 2022
In this paper, selection principles are defined and studied in the realm of irresolute topological groups. Especially, s-Menger-bounded and s-Rothberger-bounded type covering properties are introduced and studied.
