On -startpoints and -fixed points in quasi-uniform spaces: a revisit and extensions
Yaé U. Gaba
We extend the $\U$-fixed-point and $\U$-startpoint framework for quasi-uniform spaces. We reformulate the original existence framework through the filter axioms and supply a two-si…
On Fixed Point Theorems in Bipolar Metric Spaces Involving Polynomial-Type Contractions
Gopinath Janardhanan, Gunaseelan Mani, Nancy Delaila John Kennedy +1
In this paper, we investigate the existence and uniqueness of fixed points for self-mappings defined on bipolar metric spaces using a new class of contractive conditions, namely po…
Quasi-uniform type spaces
Yaé Ulrich Gaba
In this article, we introduce and investigate the concept of partial quasi-metric type space as a generalization of both partial quasi-metric and quasi-metric type spaces. We show…
A new characterization of partial metric completeness
Yaé Ulrich Gaba
In this article, we present a new characterization of the completeness of a partial metric space--which we call \textit{orbital characterization}-- using fixed point results.
Partial quasi-metric completeness via Kannan-type fixed points
Yaé Ulrich Gaba
In this short note, we obtain partial quasi-metric versions of Kannan's fixed point theorem for self-mappings. Moreover, we use these fixed points results to characterize a certain…
Chatterjea type fixed point in Partial -metric spaces
Yaé Ulrich Gaba, Collins Amburo Agyingi, Domini Jocema Leko
In this paper, we give and prove two Chatterjea type fixed point theorems on partial -metric space. We propose an extension to the Banach contraction principle on partial -me…
Fixed point on partial metric type spaces
Yaé Ulrich Gaba
In this paper, we study some new fixed point results for self maps defined on partial metric type spaces. In particular, we give common fixed point theorems in the same setting. So…
Startpoints via weak contractions
Collins Amburo Agyingi, Yaé Ulrich Gaba
Startpoints (resp. endpoints) can be defined as "oriented fixed points". They arise naturally in the study of fixed for multi-valued maps defined on quasi-metric spaces. In this ar…
Weak contractions via -sequences
Collins Amburo Agyingi, Yaé Ulrich Gaba
In this note, we discuss common fixed point for a family of self mapping defined on a metric type space and satisfying a weakly contractive condition. In our development, we make u…
-metric structures
Yaé Ulrich Gaba
In this paper, we discuss recent results about generalized metric spaces and fixed point theory. We introduce the notion of -cone metric spaces, give some topological properties…
(-order Fixed points in -metric spaces
Yaé Ulrich Gaba, Collins Amburo Agyingi
We establish three major fixed-point theorems for functions satisfying an odd power type contractive condition in G-metric spaces. We first consider the case of a single mapping, f…
-tuple fixed point in -ordered -metric spaces
Yaé Ulrich Gaba, Collins Amburo Agyingi
We use three seminal approaches in the study of fixed point theory, the so called -metrics, multidimensional fixed points and partially ordered spaces. More precisely, we extend…
-admissible functions in quasi-pseudometric type spaces
Yaé Ulrich Gaba
In this article, we give some fixed point results in left -complete quasi-pseudometric type spaces for self-mappings that are -admissible.
Common Coupled Fixed Point Theorems for Maps in a -ultra-quasi-metric Space
Collins Amburo Agyingi, Yaé Ulrich Gaba
In this article, we prove the existence of common fixed points for a pair of maps on a -spherically complete -ultra-quasi-metric space. The present article is a generalizat…
Fixed points for weak contractions in metric type spaces
Yaé Ulrich Gaba
In this article, we prove some fixed point theorems in metric type spaces. This article is just a generalization some results previously proved in \cite{niyi-gaba}. In particular,…
