More general contractions in perturbed metric spaces
Maria Nutu, Cristina Maria Pacurar
In the present paper, we introduce two new types of contractive mappings in perturbed metric spaces, namely -perturbed mappings and perturbed Kannan mappings. We prove a fixed p…
Fixed point results for contractions of polynomial type
Mohamed Jleli, Cristina Maria Pacurar, Bessem Samet
We introduce two new classes of single-valued contractions of polynomial type defined on a metric space. For the first one, called the class of polynomial contractions, we establis…
New directions in fixed point theory in -metric spaces and applications to mappings contracting perimeters of triangles
Mohamed Jleli, Cristina Maria Pacurar, Bessem Samet
We are concerned with the study of fixed points for mappings , where is a -metric space in the sense of Mustafa and Sims. After the publication of the paper […
Fixed points for three point generalized orbital triangular contractions
Cristina Maria Pacurar, Ovidiu Popescu
In this paper we introduce and study new classes of mappings in metric spaces. The main class of mappings is called generalized orbital triangular contractions and it generalizes s…
Mappings contracting triangles
Ovidiu Popescu, Cristina Maria Pacurar
The aim of the current paper is to introduce a new class of contractive mappings, which are contracting (a feature of) triangles. We prove that maps contracting triangles are conti…
Fractal interpolation in the context of prediction accuracy optimization
Alexandra Baicoianu, Cristina Gabriela Gavrilă, Cristina Maria Pacurar +1
This paper focuses on the hypothesis of optimizing time series predictions using fractal interpolation techniques. In general, the accuracy of machine learning model predictions is…
Some remarks on expansive mappings in metric spaces
Ovidiu Popescu, Cristina Maria Pacurar
The aim of this paper is to generalize the results on expansive mappings of Yesilkaya and Aydin from \cite{Yesilkaya}. We give some fixed point results for q-expansive mappings in…
Tourist route optimization in the context of Covid-19 pandemic
Cristina Maria Pacurar, Ruxandra-Gabriela Albu, Victor-Dan Pacurar
The paper presents an innovative method for tourist route planning inside a destination. The necessity of reorganizing the tourist routes within a destination comes as an immediate…
A countable fractal interpolation scheme involving Rakotch contractions
Cristina Maria Pacurar
The main result of this paper states that for a given countable system of data, there exists a countable iterated function system consisting of Rakotch contractions, such that its…
