On homotopies of morphisms and admissible mappings [PDF]

open access: yesJournal of Fixed Point Theory and Applications, 2020
AbstractThe notion of homotopy in the category of morphisms introduced by Górniewicz and Granas is proved to be equivalence relation which was not clear for years. Some simple properties are proved and a coincidence point index is described.

Admissible linear map models of linear cameras [PDF]

open access: yes2010 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2010
This paper presents a complete analytical characterization of a large class of central and non-central imaging devices dubbed linear cameras by Ponce~\cite{Pon09}. Pajdla~\cite{Pajdla02} has shown that a subset of these, the oblique cameras, can be modelled by a certain type of linear map.

On the Admissibility of the Fixed Points Set of a Mapping with Respect to Another Mapping [PDF]

open access: yesMathematics, 2021
Let (M,δ) be a metric space, f:M→M, and g:M→[0,+∞). In this paper, we obtain sufficient conditions under which the set of fixed points of f is g-admissible, i.e., Fix(f)≠∅ and Fix(f)⊂g−10. Some special cases of our main results are discussed and some examples are given.

α-admissible mappings and related fixed point theorems [PDF]

open access: yesJournal of Inequalities and Applications, 2013
AbstractIn this paper, we prove the existence and uniqueness of a fixed point for certainα-admissible contraction mappings. Our results generalize and extend some well-known results on the topic in the literature. We consider some examples to illustrate the usability of our results.MSC:46N40, 47H10, 54H25, 46T99.

Solving integral equations via admissible contraction mappings

open access: yesFilomat, 2022
In this article, we introduce a new concept of admissible contraction and prove fixed point theorems which generalize Banach contraction principle in a different way more than in the known results from the literature. The article includes an example which shows the validity of our results, and additionally we obtain a solution of integral ...

New Fixed Point Theorems for Admissible Hybrid Maps

open access: yesJournal of Function Spaces, 2022
The aim of this work is to investigate the concept of a new hybrid Suzuki contractive by using the Rus-Reich-Ćirić-type interpolative mappings in b -metric spaces. We seek the presence and uniqueness of a fixed point of such new contraction type mappings and prove ...

On Wong Type Contractions

open access: yesMathematics, 2020
In this paper, by using admissible mapping, Wong type contraction mappings are extended and investigated in the framework of quasi-metric spaces to guarantee the existence of fixed points. We consider examples to illustrate the main results.

On {$\alpha _{\,\beta }$}-contractive and admissible mappings

open access: yesMiskolc Mathematical Notes, 2018
Summary: In this paper, we introduce the concept of a pair $(f,h)$ called upper class of type II and $\alpha_{\,\beta}$-contractive mappings. We obtain that all the corresponding established results of \textit{N. Hussain} et al. [J. Inequal. Appl. 2013, Paper No. 114, 11 p. (2013; Zbl 1293.54023)] are immediate consequences of our main result. Our main
