1. Some Fixed Point Results for F -- G--Contraction in F--Metric Spaces Endowed With a Graph.

Author

Faraji, H. and Radenović, S.

Subjects
*FIXED point theory, *MATHEMATICS, *GRAPHIC methods, *MATHEMATICS theorems, *METRIC spaces, *METRIC geometry
Abstract

In this paper, we introduce the concept of F--G--contraction mappings in F-metric spaces endowed with a graph and give some fixed point results for such contractions. Our results are generalization of some famous theorem in metric spaces to F--metric spaces endowed with a graph. Also, we give some examples that support obtained theoretical results.

2. A common fixed point theorem of Jungck in rectangular b-metric spaces.

Author

Mitrović, Z. and Radenović, S.

Subjects
*METRIC spaces, *FIXED point theory, *GENERALIZED spaces, *TOPOLOGY, *MATHEMATICS
Abstract

We give a proof for the common fixed point theorem of Jungck in rectangular b-metric spaces. As a corollary, we obtain well known common fixed point theorems in b-metric spaces. [ABSTRACT FROM AUTHOR]

3. SOME RESULTS ON WEAKLY CONTRACTIVE MAPS.

Author

RADENOVIĆ, S., KADELBURG, Z., JANDRLIĆ, D., and JANDRLIĆ, A.

Subjects
*MATHEMATICAL mappings, *MATHEMATICS, *ALGEBRA, *FIXED point theory, *NONLINEAR operators
Abstract

In this paper direct proofs of some common fixed point results for two and three mappings under weak contractive conditions are given. Some of these results are improved by using different arguments of control functions. Examples are presented showing that some generalizations can not be obtained and also that our results are distinct from the existing ones. [ABSTRACT FROM AUTHOR]

4. ON αβ-CONTRACTIVE AND ADMISSIBLE MAPPINGS.

Author

CHANDOK, S., ANSARI, A. H., DOŠENOVIĆ, T., and RADENOVIĆ, S.

Subjects
*POINT mappings (Mathematics), *FIXED point theory, *BANACH algebras, *TOPOLOGICAL algebras, *MATHEMATICS
Abstract

In this paper, we introduce the concept of a pair (f, h) called upper class of type II and αβ-contractive mappings. We obtain that all the corresponding established results of Hussain et al. [7] are immediately consequences of our main result. Our main result generalizes and modifies several existing results in literature. Also, an example is given to support the main result.

5. Graphical metric space: a generalized setting in fixed point theory

Abstract

Building on recent ideas of Jachymski, we work on the notion of graphical metric space and prove an analogous result for the contraction mapping principle. In particular, the triangular inequality is replaced by a weaker one, which is satisfied by only those points which are situated on some path included in the graphical structure associated with the space. Some consequences, examples and an application to integral equations are presented to confirm the significance and unifying power of obtained generalizations.
