Remarks on the Preservation of the Almost Fixed Point Property Involving Several Types of Digitizations [PDF]

open access: yesMathematics, 2019
This paper explores a certain relationship between the almost fixed point property (AFPP for short) of a compact and n-dimensional Euclidean space and that of its digitized space.

Digital k-Contractibility of an n-Times Iterated Connected Sum of Simple Closed k-Surfaces and Almost Fixed Point Property [PDF]

open access: yesMathematics, 2020
The paper firstly establishes the so-called n-times iterated connected sum of a simple closed k-surface in Z 3 , denoted by C k n , k ∈ { 6 , 18 , 26 } .

Fixed point theorems for multifunctions having KKM property on almost convex sets

open access: yesJournal of Mathematical Analysis and Applications, 2006
The authors consider the class KKM(\(X,Y\)) of multivalued maps \(T:X\multimap Y\) having the KKM property, which means that for every generalized KKM mapping \(F:X\multimap Y\) with respect to \(T\) (definition below) the family \(\{\overline{F(x)} : x\in X\}\) has the finite intersection property.

Convexity in Helly Graphs: Selection and Almost Fixed Point Properties for Multifunctions

open access: yesElectronic Notes in Theoretical Computer Science, 2006
AbstractIn this paper, a notion of convexity structure for graphs, called neighbourhood convexity, is introduced. It is shown that neighbourhood convexity is exactly the graph convexity for Helly graphs to be 2-Helly. We then consider various neighbourhood-convexity almost fixed point properties for Helly graphs.

The almost fixed point property for nonexpansive mappings [PDF]

open access: yesProceedings of the American Mathematical Society, 1983
It is shown that a closed convex subset of a reflexive Banach space has the almost fixed point property for nonexpansive mappings if and only if it is linearly bounded.

Approximate Fixed Point Theorems for the Class of Almost S-KKM𝒞 Mappings in Abstract Convex Uniform Spaces [PDF]

open access: yesFixed Point Theory and Applications, 2009
We use a concept of abstract convexity to define the almost S-KKM𝒞 property, al-S-KKM𝒞(X,Y) family, and almost Φ-spaces. We get some new approximate fixed point theorems and fixed point theorems in almost Φ-spaces.

Besicovitch Almost Periodic Solutions of Abstract Semi-Linear Differential Equations with Delay

open access: yesMathematics, 2022
In this paper, first, we give a definition of Besicovitch almost periodic functions by using the Bohr property and the Bochner property, respectively; study some basic properties of Besicovitch almost periodic functions, including composition theorem ...
