Conditions of regularity in cone metric spaces

Applied Mathematics and Computation, 2011
The authors prove some fixed points results on cone metric spaces for maps satisfying general contractive type conditions. Their results extend some results of \textit{H.-D. Nguyen} [J. Math. Anal. Appl. 187, 76--90 (1994; Zbl 0810.54034)] from metric spaces to Banach space valued cone metric spaces.

Topology of soft cone metric spaces

AIP Conference Proceedings, 2017
In Simsek’s paper it was introduced a concept of soft cone metric space via soft elements and some fixed point theorems in soft cone metric space were provided. In this work, we examine topological structures such as open ball, soft neighbourhood and soft open set in soft metric spaces and their some properties, and prove that every soft cone metric ...

On the metrizability of cone metric spaces

Topology and Its Applications, 2011
We have shown in this paper that a (complete) cone metric space (X,E,P,d) is indeed (completely) metrizable for a suitable metric D. Moreover, given any finite number of contractions f1,…,fn on the cone metric space (X,E,P,d), D can be defined in such a ...

Common fixed points in cone metric spaces

Rendiconti Del Circolo Matematico Di Palermo, 2007
In this paper we consider a notion of g-weak contractive mappings in the setting of cone metric spaces and we give results of common fixed points. This results generalize some common fixed points results in metric spaces and some of the results of Huang ...

KKM mappings in cone b-metric spaces

Computers and Mathematics With Applications, 2011
In this paper we establish some topological properties of the cone b-metric spaces and then improve some recent results about KKM mappings in the setting of a cone b-metric space.

On cone metric spaces: A survey

Nonlinear Analysis: Theory, Methods & Applications, 2011
The article is a very useful survey of different results connected with fixed point theorems in cone metric (\(K\)-metric) spaces \((X,d)\) with cone metric \(d(\cdot,\cdot)\) taking values in a cone \(P\) in a Banach space \(E\). In particular, the authors, in a short and easy way, prove that numerous fixed point results in cone metric spaces obtained
