Application of the Fisher-Rao metric to ellipse detection [PDF]

open access: yes, 2007
The parameter space for the ellipses in a two dimensional image is a five dimensional manifold, where each point of the manifold corresponds to an ellipse in the image. The parameter space becomes a Riemannian manifold under a Fisher-Rao metric, which is

Some Fixed Point Theorem for Mapping on Complete G-Metric Spaces

open access: yesFixed Point Theory and Applications, 2008
We prove some fixed point results for mapping satisfying sufficient conditions on complete G-metric space, also we showed that if the G-metric space (X,G) is symmetric, then the existence and uniqueness of these fixed point results follow from well ...

On fixed point results for alpha-implicit contractions in quasi-metric spaces and consequences

open access: yesNonlinear Analysis, 2016
In this paper, we prove some fixed point results involving α-implicit contractions in quasi-metric spaces. Moreover, we provide some known results on G-metric spaces.

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.

Estimating the weight of metric minimum spanning trees in sublinear time [PDF]

open access: yes, 2008
In this paper we present a sublinear-time $(1+\varepsilon)$-approximation randomized algorithm to estimate the weight of the minimum spanning tree of an $n$-point metric space. The running time of the algorithm is $\widetilde{\mathcal{O}}(n/\varepsilon^{\

Fixed Point Theorems in General Metric Space with an Application

open access: yesمجلة بغداد للعلوم, 2021
This paper aims to prove an existence theorem for Voltera-type equation in a generalized G- metric space, called the -metric space, where the fixed-point theorem in - metric space is discussed and its application.

Property P in G-metric spaces

open access: yesFixed Point Theory and Applications, 2010
The authors establish two fixed point theorems for some contractive-type maps on complete \(G\)-metric spaces. It is also shown that if \((X,G)\) is a complete \(G\)-metric space and \(T\) is a self-map of \(X\) satisfying the hypotheses of any of the two theorems then the maps \(F^n\) have the same fixed point set, for all \(n\in \mathbb{N}\).

On Generalized Rational α−Geraghty Contraction Mappings in G−Metric Spaces

open access: yesJournal of Mathematics, 2021
In this paper, we discuss about various generalizations of α−admissible mappings. Furthermore, we extend the concept of α−admissible to generalize rational α−Geraghty contraction in G−metric space.
