Some Common Coupled Fixed Point Results for Generalized Contraction in Complex-Valued Metric Spaces

2013

We introduce and study the notion of common coupled fixed points for a pair of mappings in complex valued metric space and demonstrate the existence and uniqueness of the common coupled fixed points in a complete complex-valued metric space in view of diverse contractive conditions. In addition, our investigations are well supported by nontrivial examples.

Coincidence and fixed points for contractions and cyclical contractions in partial metric spaces

2012

Abstract We prove some coincidence and common fixed point results for three mappings satisfying a generalized weak contractive condition in ordered partial metric spaces. As application of the presented results, we give a unique fixed point result for a mapping satisfying a weak cyclical contractive condition. We also provide some illustrative examples.

A new Cartan-type property and strict quasicoverings when p = 1 in metric spaces

2018

In a complete metric space that is equipped with a doubling measure and supports a Poincar\'e inequality, we prove a new Cartan-type property for the fine topology in the case $p=1$. Then we use this property to prove the existence of $1$-finely open \emph{strict subsets} and \emph{strict quasicoverings} of $1$-finely open sets. As an application, we study fine Newton-Sobolev spaces in the case $p=1$, that is, Newton-Sobolev spaces defined on $1$-finely open sets.

Common fixed points of mappings satisfying implicit contractive conditions

2012

In this article we obtain, in the setting of metric spaces or ordered metric spaces, coincidence point, and common fixed point theorems for self-mappings in a general class of contractions defined by an implicit relation. Our results unify, extend, generalize many related common fixed point theorems from the literature. Mathematics Subject Classification (2000): 47H10, 54H25.

A Coupled Fixed Point Theorem in Fuzzy Metric Space Satisfying ϕ-Contractive Condition

2013

The intent of this paper is to prove a coupled fixed point theorem for two pairs of compatible and subsequentially continuous (alternately subcompatible and reciprocally continuous) mappings, satisfyingϕ-contractive conditions in a fuzzy metric space. We also furnish some illustrative examples to support our results.

Fixed point theory for cyclic weak ϕ-contraction in fuzzy metric spaces

2012

In this paper, we introduce cyclic weak $\phi-$contractions in fuzzy metric spaces and utilize the same to prove some results on existence and uniqueness of fixed point in fuzzy metric spaces. Some related results are also proved besides furnishing illustrative examples.

Set-valued mappings in partially ordered fuzzy metric spaces

2014

Abstract In this paper, we provide coincidence point and fixed point theorems satisfying an implicit relation, which extends and generalizes the result of Gregori and Sapena, for set-valued mappings in complete partially ordered fuzzy metric spaces. Also we prove a fixed point theorem for set-valued mappings on complete partially ordered fuzzy metric spaces which generalizes results of Mihet and Tirado. MSC:54E40, 54E35, 54H25.

On the use of a metric-space search algorithm (AESA) for fast DTW-based recognition of isolated words

1988

The approximating and eliminating search algorithm (AESA) presented was recently introduced for finding nearest neighbors in metric spaces. Although the AESA was originally developed for reducing the time complexity of dynamic time-warping isolated word recognition (DTW-IWR), only rather limited experiments had been previously carried out to check its performance in this task. A set of experiments aimed at filling this gap is reported. The main results show that the important features reflected in previous simulation experiments are also true for real speech samples. With single-speaker dictionaries of up to 200 words, and for most of the different speech parameterizations, local metrics, a…

Dyskryminacja ze względu na bezwyznaniowość w pracy. Rozważania na kanwie orzeczeń sądowych zapadłych w sprawie dotyczącej G.J

2021

Kazus G. J. dotyczy dyskryminacji nauczycielki, która dwukrotnie zdjęła ze ściany pokoju nauczycielskiego krzyż. Swoje zachowanie tłumaczyła negatywnymi skojarzeniami z tym symbolem religijnym. Została ukarana dyscyplinarnie przez dyrekcję szkoły, co uznała za dyskryminację jej osoby ze względu na jej bezwyznaniowość. Złożyła do sądu pozew o odszkodowanie z tytułu molestowania w miejscu pracy i uzyskała korzystne dla siebie rozstrzygniecie. Po prawomocnym zakończeniu sprawy wniesiona została skarga nadzwyczajna do Sądu Najwyższego z wnioskiem o uchylenie wyroku całości i orzeczenie przez Sąd Najwyższy co do istoty sprawy. W powyższej sprawie przedmiotem rozstrzygnięcia nie była kwestia eksp…

Participative Planning Processes in the Absence of the (Public) Space of Democracy

2010

Abstract This article aims to investigate the role, limits and opportunities of participation programmes in a local political context where consensus-building and inclusionary practices are not high priorities. A public housing neighbourhood in Palermo is used as a case study in order to critically highlight the ambiguous role that participative practices tend to play in fragile contexts. The case study also highlights the need for some preconditions for effective participatory practices in planning. These preconditions are focused on Arendt's notion of the ‘space of democracy’. Some concepts developed by Hannah Arendt will be used to explain the necessity of these preconditions, and their …
