2. Gerghaty type results via simulation and $\mathcal{C}$-class functions with application

Author

Hussain, Azhar, Ishfaq, Muhammad, Kanwal, Tanzeela, and Radenović, Stojan

Subjects
Mathematics - Functional Analysis, 47H10
Abstract

In this paper we study the notion of Gerghaty type contractive mapping via simulation function along with $\mathcal{C}$-class functions and prove the existence of several fixed point results in ordinary and partially ordered metric spaces. An example is given to show the validity of our results given herein. Moreover, existence of solution of two-point boundary value second order nonlinear differential equation is obtain., Comment: arXiv admin note: text overlap with arXiv:1810.09969

4. A new survey: Cone metric spaces

Abstract

The purpose of this new survey paper is, among other things, to collect in one place most of the articles on cone (abstract, K-metric) spaces, published after 2007. This list can be useful to young researchers trying to work in this part of functional and nonlinear analysis. On the other hand, the existing review papers on cone metric spaces are updated. The main contribution is the observation that it is usually redundant to treat the case when the underlying cone is solid and non-normal. Namely, using simple properties of cones and Minkowski functionals, it is shown that the problems can be usually reduced to the case when the cone is normal, even with the respective norm being monotone. Thus, we offer a synthesis of the respective fixed point problems arriving at the conclusion that they can be reduced to their standard metric counterparts. However, this does not mean that the whole theory of cone metric spaces is redundant, since some of the problems remain which cannot be treated in this way, which is also shown in the present article., Comment: 27 pages

7. Unified multi-tupled fixed point theorems involving monotone property in ordered metric spaces

Author

Alam, Aftab, Imdad, Mohammad, and Radenovic, Stojan

Subjects
Mathematics - Functional Analysis
Abstract

In this paper, we introduce a generalized notion of monotone property and prove some results regarding existence and uniqueness of multi-tupled fixed points for nonlinear contraction mappings satisfying monotone property in ordered complete metric spaces. Our results unify several classical and well known n-tupled (including coupled, tripled and quadruple ones) fixed point results existing in literature., Comment: arXiv admin note: substantial text overlap with arXiv: 1601.02509

Abstract

In this work, we will define a new type metric with degree m and m+1 points which is called m-hemi metric as a generalization of 2-metric spaces. We will give and prove some topological properties. Also, Banach contraction mapping principle was proved and an application to Fredholm integral equation were gived in hemi metric spaces. [ABSTRACT FROM AUTHOR]

17. An alternative and easy approach to fixed point results via simulation functions

Abstract

We discuss, extend, improve and enrich results on simulation functions established by several authors. Furthermore, by using Lemma 2.1 of Radenovic et al. [Bull. Iran. Math. Soc., 2012, 38, 625],we get much shorter and nicer proofs than the corresponding ones in the existing literature.

32. The First Rational Type Revised Fuzzy-Contractions in Revised Fuzzy Metric Spaces with an Applications.

Author

Muraliraj, Angamuthu, Thangathamizh, Ravichandran, Popovic, Nikola, Savic, Ana, and Radenovic, Stojan

Subjects
METRIC spaces, NONLINEAR integral equations, CONTRACTIONS (Topology), COINCIDENCE theory
Abstract

This paper aims to introduce the concept of rational type revised fuzzy-contraction mappings in revised fuzzy metric spaces. Fixed point results are proven under the rational type revised fuzzy-contraction conditions in revised fuzzy metric spaces with illustrative examples provided to support the results. A significant role will be played by this new concept in the theory of revised fuzzy fixed point results, and it can be generalized for different contractive type mappings in the context of revised fuzzy metric spaces. Additionally, an application of a nonlinear integral type equation is presented to obtain the existing result in a unique solution to support the work. [ABSTRACT FROM AUTHOR]
