A Few Notes on Formal Balls [PDF]

open access: yesLogical Methods in Computer Science, 2017
Using the notion of formal ball, we present a few new results in the theory of quasi-metric spaces. With no specific order: every continuous Yoneda-complete quasi-metric space is sober and convergence Choquet-complete hence Baire in its $d$-Scott ...

Common Fixed Point Theorems for T-Hardy-Rodgers Contraction Mappings in Complete Cone b-Metric Spaces with an Application

open access: yesTopological Algebra and its Applications, 2021
This paper presents some fixed point theorems for T-Hardy-Rodgers contraction mappings in complete cone b-metric spaces without the assumption of normality conditions.

Some New Results on F-Contractions in 0-Complete Partial Metric Spaces and 0-Complete Metric-Like Spaces

open access: yesFractal and Fractional, 2021
Within this manuscript we generalize the two recently obtained results of O. Popescu and G. Stan, regarding the F-contractions in complete, ordinary metric space to 0-complete partial metric space and 0-complete metric-like space.

Fixed Point Theorems on Complete Quasi Metric Spaces Via C-class and A-Class Functions [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2020
In this paper, we present some fixed point theorems for single valued mappings on $K$-complete, $M$-complete and Symth complete quasi metric spaces. Here, for contractive condition, we consider some altering distance functions together with functions ...

Some Properties of Lebesgue Fuzzy Metric Spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2021
In this paper, we establish a sequential characterisation of Lebesgue fuzzy metric and explore the relationship between Lebesgue, weak $G$-complete and compact fuzzy metric spaces.

w-Distances on Fuzzy Metric Spaces and Fixed Points

open access: yesMathematics, 2020
We propose a notion of w-distance for fuzzy metric spaces, in the sense of Kramosil and Michalek, which allows us to obtain a characterization of complete fuzzy metric spaces via a suitable fixed point theorem that is proved here.

Some problems on selections for hyperspace topologies

open access: yesApplied General Topology, 2004
The theory of hyperspaces has attracted the attention of many mathematicians who have found a large variety of its applications during the last decades.

A note on Gromov-Hausdorff-Prokhorov distance between (locally) compact measure spaces [PDF]

open access: yes, 2012
We present an extension of the Gromov-Hausdorff metric on the set of compact metric spaces: the Gromov-Hausdorff-Prokhorov metric on the set of compact metric spaces endowed with a finite measure. We then extend it to the non-compact case by describing a
