Sobolev Spaces in Extended Metric-Measure Spaces [PDF]

open access: yes, 2021
These lecture notes contain an extended version of the material presented in the C.I.M.E. summer course in 2017. The aim is to give a detailed introduction to the metric Sobolev theory. The notes are divided in four main parts.

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.

Matkowski's type theorems for generalized contractions on (ordered) partial metric spaces

open access: yesApplied General Topology, 2011
We obtain extensions of Matkowski's fixed point theorem for generalized contractions of Ciric's type on 0-complete partial metric spaces and on ordered 0-complete partial metric spaces, respectively.

STATISTICAL CONVERGENCE IN A BICOMPLEX VALUED METRIC SPACE

open access: yesUral Mathematical Journal, 2023
In this paper, we study some basic properties of bicomplex numbers. We introduce two different types of partial order relations on bicomplex numbers, discuss bicomplex valued metric spaces with respect to two different partial orders, and compare them ...

Fixed Point Theory in b-convex Metric Spaces

open access: yesJournal of Harbin University of Science and Technology, 2021
b-metric spaces are a kind of generalized metric spaces,which have attracted extensive attention of scholars at home and abroad in recent years. In this paper,the convex structure is firstly introduced in b-metric spaces,and consequently the notion of ...

A characterization of p-complete fuzzy metric spaces [PDF]

open access: yes, 2022
[EN] George and Veeramani characterized complete fuzzy metric spaces ¿ by means of nested sequences of closed sets of X which have fuzzy diameter zero. According to the concept of p-convergence due to D. Mihet, an appropriate concept of p-Cauchy sequence

Relation-Theoretic Contraction Principle In Metric Spaces Using Multiplicative Contraction

open access: yesRatio Mathematica, 2023
Alam and Imdad have presented a novel application of the Banach contraction principle on a complete metric spaces with a binary relation. We have extended the concept of binary relation with the multiplicative contraction in a complete metric spaces.

A new approach on generalized quasimetric spaces induced by partial metric spaces

open access: yesJournal of Inequalities and Applications, 2022
In this paper, we introduce the concept of generalized quasimetric spaces by a new approach, and present some examples in the partial metric spaces. Furthermore, we obtain some results on (strong) complete partial metric spaces.

New Results on F-Contractions in Complete Metric Spaces

open access: yesMathematics, 2021
The main purpose of this paper is to improve, generalize, unify, extend and enrich the recent results established by Dung and Hang (2015), Piri and Kumam (2014, 2016), and Singh et al. (2018). In our proofs, we only use the property (F1) of Wardowski’s F-

Density and extension of differentiable functions on metric measure spaces

open access: yes, 2021
We consider vector valued mappings de ned on metric measure spaces with a measurable differ-entiable structure and study both approximations by nicer mappings and regular extensions of the givenmappings when de ned on closed subsets.
