When is a space Menger at infinity?

Applied General Topology, 2015
We try to characterize those Tychonoff spaces X such that $\beta X\setminus X$ has the Menger property.

Fréchet differentiation between Menger probabilistic normed spaces [PDF]

Proyecciones (Antofagasta), 2017
In this paper, we define and study Menger weakly and strongly P-convergent sequences and then Menger probabilistic continuity. We also display Frechet differentiation of nonlinear operators between Menger probabilistic normed spaces.

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

Ibis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Amacrine cell inputs to OFF midget ganglion cells in macaque retina

The Journal of Physiology, EarlyView.
Abstract figure legend The goal of this study was to explain the findings from physiological studies that OFF midget ganglion cells had larger receptive field centers than expected from their dendritic field diameters. First, we confirmed that OFF mRGCs (OFF MGC) receive input from diffuse bipolar cells (DB) as well as OFF midget bipolar cells (FMB ...

Fixed point results in Menger probabilistic suprametric spaces with an application to fractional differential equations

Fixed Point Theory and Algorithms for Sciences and Engineering
In this paper, our objective is to extend the concept of Menger probability metric space by presenting its corresponding structure, namely the Menger probability suprametric space. Additionally, we investigate several topological properties of this space

A common fixed point theorem in Menger space using implicit relation [PDF]

Surveys in Mathematics and its Applications, 2013
The main purpose of this paper is to prove a common fixed point theorem for two pairs of weakly compatible mappings in Menger space using implicit relation.

On nearly Hurewicz spaces

Open Mathematics, 2019
In this paper we define and investigate nearly Hurewicz spaces and their star version. It is shown that a nearly Hurewicz space fits between Hurewicz and almost Hurewicz spaces.

Geometric Sobolev-like embedding using high-dimensional Menger-like curvature

, 2013
We study a modified version of Lerman-Whitehouse Menger-like curvature defined for m+2 points in an n-dimensional Euclidean space. For 1

On the Number of Embeddings of Minimally Rigid Graphs

, 2002
Rigid frameworks in some Euclidian space are embedded graphs having a unique local realization (up to Euclidian motions) for the given edge lengths, although globally they may have several.
