On a Theorem of Khan in a Generalized Metric Space [PDF]
International Journal of Analysis, 2013 Existence and uniqueness of fixed points are established for a mapping satisfying a contractive condition involving a rational expression on a generalized metric space. Several particular cases and applications as well as some illustrative examples are given.

Inequalities on Generalized Sasakian Space Forms
Journal of Function Spaces, 2021 In this paper, we find the second variational formula for a generalized Sasakian space form admitting a semisymmetric metric connection. Inequalities regarding the stability criteria of a compact generalized Sasakian space form admitting a semisymmetric ...

Generalized fixed point theorems on metric spaces [PDF]
Mathematica Moravica, 2022 In this paper, we establish some fixed point theorems for single valued and multi-valued mappings on a complete metric space. Suzuki's and some other fixed point theorems are generalized by taking a more general contractive condition for single valued ...

On 3-Dimensional Contact Metric Generalized (k,μ)-Space Forms [PDF]
International Journal of Mathematics and Mathematical Sciences, 2014 The present paper deals with a study of 3-dimensional contact metric generalized (k,μ)-space forms. We obtained necessary and sufficient condition for a 3-dimensional contact metric generalized (k,μ)-space form with Qϕ=ϕQ to be of constant curvature.

Probabilistic Generalized Metric Spaces and Nonlinear Contractions
Demonstratio Mathematica, 2016 We give a probabilistic generalization of the theory of generalized metric spaces [2]. Then, we prove a fixed point theorem for a self-mapping of a probabilistic generalized metric space, satisfying the very general nonlinear contraction condition ...

Nadler’s fixed point theorem in ν-generalized metric spaces
Fixed Point Theory and Applications, 2017 We extend Nadler’s fixed point theorem to ν-generalized metric spaces. Through the proof of the above extension, we understand more deeply the mathematical structure of a ν-generalized metric space.

Some fixed point results in complete generalized metric spaces
Karpatsʹkì Matematičnì Publìkacìï, 2018 The Banach contraction principle is the most important result. This principle has many applications and some authors was interested in this principle in various metric spaces as Brianciari.

Ultra Generalized Metric Space [PDF]
, 2020 In this paper, for n is a natural number such that n→∞, we described ultra generalized metric space as an ultra generalization of a metric space in such a way that the triangle inequality is replaced by similar ones which involve n unit points instead of

On the topology of D‐metric spaces and generation of D‐metric spaces from metric spaces [PDF]
International Journal of Mathematics and Mathematical Sciences, 2004 An example of a D‐metric space is given, in which D‐metric convergence does not define a topology and in which a convergent sequence can have infinitely many limits. Certain methods for constructing D‐metric spaces from a given metric space are developed and are used in constructing (1) an example of a D‐metric space in which D‐metric convergence ...

Reordering buffers for general metric spaces [PDF]
Proceedings of the thirty-ninth annual ACM symposium on Theory of computing, 2007 In the reordering buffer problem, we are given an input sequence of requests for service each of which corresponds to a point in a metric space. The cost of serving the requests heavily depends on the processing order. When serving a request the cost is equal to the distance, in the metric space, between this request and the previously served request ...
