UNIQUE FIXED POINT THEOREMS FOR CONTRACTIVE MAPS TYPE IN T 0 -QUASI-METRIC SPACES [PDF]

open access: yes, 2014
In [2], Agyingi proved that every generalized contractive mapping defined in a q-spherically complete T 0 -ultra-quasi-metric space has a unique fixed point.

Some approximate fixed point results and application on graph theory for partial (h-F)-generalized convex contraction mappings with special class of functions on complete metric space

open access: yesThe Journal of Nonlinear Sciences and Applications, 2017
Summary: In this paper, we introduce a new concept called partial (h-F)-generalized (and (h-F)-subgeneralized) convex contractions of order 3 (and with rank 3) using some auxiliary functions. Also we present some approximate fixed point results in metric space and approximate fixed point results in metric space endowed with a graph.

On Multi-Metric Spaces [PDF]

open access: yes, 2005
A Smarandache multi-space is a union of n spaces with some additional conditions holding. Combining Smarandache multi-spaces with classical metric spaces, the conception of multi-metric spaces is introduced.

Lipschitz (q, p)-Summing Maps from C(K)-Spaces to Metric Spaces [PDF]

open access: yes, 2023
[EN] Variants of the notion of (q, p)-summing operator are introduced in the setting of Lipschitz mappings acting between metric spaces. Some classes of these operators from C(K)-spaces to metric spaces are studied.

On the dynamics of sup-norm non-expansive maps [PDF]

open access: yes, 2005
We present several results for the periods of periodic points of sup-norm non-expansive maps. In particular, we show that the period of each periodic point of a sup-norm non-expansive map $f\colon M\to M$, where $M\subset \mathbb{R}^n$, is at most ...

Hyperconvexity and endpoints in T₀-quasi-metric spaces [PDF]

open access: yes, 2013
Over the last decades much progress has been made in the investigation of hyperconvexity in metric spaces. Recently Kemajou and others have published an article concerning hyperconvexity in T₀-quasi-metric spaces.

Fixed point theory in metric type spaces

open access: yes, 2015
Written by a team of leading experts in the field, this volume presents a self-contained account of the theory, techniques and results in metric type spaces (in particular in G-metric spaces); that is, the text approaches this important area of fixed ...

Fixed Point Theorems for g-Monotone Maps on Partially Ordered S-Metric Spaces [PDF]

open access: yes, 2014
In this paper, we prove some fixed point theorems for g-monotone maps on partially ordered S-metric spaces. Our results generalize fixed point theorems in [1] and [7] for maps on metric spaces to the structure of S-metric spaces.
