Asymptotic behavior of inexact infinite products of nonexpansive mappings [PDF]

open access: yes, 2021
We analyze the asymptotic behavior of inexact infinite products of non- expansive mappings, which take a nonempty closed subset of a complete metric space into the space, in the case where the errors are sufficiently small.

Porosity-based methods for solving stochastic feasibility problems [PDF]

open access: yes, 2022
The notion of porosity is well known in Optimization and Nonlinear Analysis. Its importance is brought out by the fact that the complement of a σ-porous subset of a complete pseudo-metric space is a residual set, while the existence of the latter is ...

Equivalents of maximum principles for several spaces

open access: yesTopological Algebra and its Applications, 2022
According to our long-standing Metatheorem, certain maximum theorems can be equivalently reformulated to various types of fixed point theorems, and conversely.

so-metrizable spaces and images of metric spaces

open access: yesOpen Mathematics, 2021
so-metrizable spaces are a class of important generalized metric spaces between metric spaces and snsn-metrizable spaces where a space is called an so-metrizable space if it has a σ\sigma -locally finite so-network.

Some Common Fixed Point Results for 𝒵E−Contractions in Modular b−Metric Spaces

open access: yesTopological Algebra and its Applications, 2022
The primary purpose of this study is to demonstrate some common fixed point theorems for diverse E−contractions involving generalized Proinov-simulation functions in the setting of modular b−metric spaces.

Characterizations of quasi-metric and G-metric completeness involving w-distances and fixed points

open access: yesDemonstratio Mathematica, 2022
Involving ww-distances we prove a fixed point theorem of Caristi-type in the realm of (non-necessarily T1{T}_{1}) quasi-metric spaces. With the help of this result, a characterization of quasi-metric completeness is obtained.

Remarks on the generalized interpolative contractions and some fixed-point theorems with application

open access: yesOpen Mathematics, 2022
In this manuscript, some remarks on the papers [H. A. Hammad, P. Agarwal, S. Momani, and F. Alsharari, Solving a fractional-order differential equation using rational symmetric contraction mappings, Fractal Fract. 5 (2021), 159] and [A. Hussain, F. Jarad,

Common fixed points of R-weakly commuting maps in generalized metric spaces [PDF]

open access: yes, 2011
In this paper, using the setting of a generalized metric space, a unique common fixed point of four R-weakly commuting maps satisfying a generalized contractive condition is obtained. We also present example in support of our result.

Intermediate Value Property for the Assouad Dimension of Measures

open access: yesAnalysis and Geometry in Metric Spaces, 2020
Hare, Mendivil, and Zuberman have recently shown that if X ⊂ ℝ is compact and of non-zero Assouad dimension dimA X, then for all s > dimA X, X supports measures with Assouad dimension s. We generalize this result to arbitrary complete metric spaces.

On statistical convergence in quasi-metric spaces

open access: yesDemonstratio Mathematica, 2019
A quasi-metric is a distance function which satisfies the triangle inequality but is not symmetric in general. Quasi-metrics are a subject of comprehensive investigation both in pure and applied mathematics in areas such as in functional analysis ...
