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…
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…
