Fixed Point Results on Multiplicative Semi-Metric Space

Journal of Scientific Research, 2020
  In this paper we introduce the notion of the Multiplicative Semi-Metric Space and proved common fixed point theorems. We establish fixed point theorems for four self-maps which can be extended to derive common fixed point theorems involving any finite number of mappings in Multiplicative Semi Metric Space. Further examples are discussed to show

Stationary random metrics on hierarchical graphs via $(\min,+)$-type recursive distributional equations

, 2015
This paper is inspired by the problem of understanding in a mathematical sense the Liouville quantum gravity on surfaces. Here we show how to define a stationary random metric on self-similar spaces which are the limit of nice finite graphs: these are ...

Skeletally Dugundji spaces

, 2012
We introduce and investigate the class of skeletally Dugundji spaces as a skeletal analogue of Dugundji space. The main result states that the following conditions are equivalent for a given space $X$: (i) $X$ is skeletally Dugundji; (ii) Every ...

Universality for critical heavy-tailed network models: Metric structure of maximal components

, 2020
We study limits of the largest connected components (viewed as metric spaces) obtained by critical percolation on uniformly chosen graphs and configuration models with heavy-tailed degrees.

Common Fixed Points of Locally Contractive Mappings in Multiplicative Metric Spaces with Application

International Journal of Mathematics and Mathematical Sciences, 2015
The aim of this paper is to present common fixed point results of quasi-weak commutative mappings on a closed ball in the framework of multiplicative metric spaces. Example is presented to support the result proved herein.

An algebraic characterization of complete inner product spaces

International Journal of Mathematics and Mathematical Sciences, 1986
We present a characterization of complete inner product spaces using en involution on the set of all bounded linear operators on a Banach space. As a metric conditions we impose a “multiplicative” property of the norm for hermitain operators.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

On multiplicative modular metric spaces of Kaplan et al.: corrections and clarifications

Fixed Point Theory and Algorithms for Sciences and Engineering
Kaplan et al. (J. Inequal. Appl. 2025:54, 2025) introduced the notion of multiplicative modular metric spaces, motivated by the framework of multiplicative metric spaces (Özavşar and Cevikel in J. Eng. Technol. Appl. Sci.
