Fixed point theorem for new type of auxiliary functions

Acta Universitatis Sapientiae: Mathematica, 2020
In this paper, we present some fixed point results satisfying generalized contractive condition with new auxiliary function in complete metric spaces. More precisely, the structure of the paper is the following.

Fixed point results for single and set-valued α-η-ψ-contractive mappings

, 2013
Samet et al. (Nonlinear Anal. 75:2154-2165, 2012) introduced α-ψ-contractive mappings and proved some fixed point results for these mappings. More recently Salimi et al. (Fixed Point Theory Appl.

Convergence theorems for a family of multivalued nonexpansive mappings in hyperbolic spaces

Open Mathematics, 2016
In this article we modify an iteration process to prove strong convergence and Δ— convergence theorems for a finite family of nonexpansive multivalued mappings in hyperbolic spaces.

Tripled best proximity point in complete metric spaces

Open Mathematics, 2020
In this paper, we introduce a new type of contraction to seek the existence of tripled best proximity point results. Here, using the new contraction and P-property, we generalize and extend results of W. Shatanawi and A. Pitea and prove the existence and

A generalized weak contraction principle with applications to coupled coincidence point problems

, 2013
In this paper we establish some coincidence point results for generalized weak contractions with discontinuous control functions. The theorems are proved in metric spaces with a partial order.

A simple case within Nash-Moser-Ekeland theory

, 2018
We present simple and direct proof to an important case of Nash-Moser-Ekeland theorem.Comment: In this third version we have made numerous improvements inspired by the referee, like correcting the definition of directional derivative to the standard ...

α-admissible mappings and related fixed point theorems

, 2013
In this paper, we prove the existence and uniqueness of a fixed point for certain α-admissible contraction mappings. Our results generalize and extend some well-known results on the topic in the literature.

Common fixed points for single-valued and multi-valued maps satisfying a generalized contraction in G-metric spaces

, 2012
In this article, we establish some common fixed point theorems for a hybrid pair {g, T} of single valued and multi-valued maps satisfying a generalized contractive condition defined on G-metric spaces. Our results unify, generalize and complement various

Fixed point results for contractions of polynomial type

Demonstratio Mathematica
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 establish two fixed point theorems.

Fixed points for singlevalued operators with respect to tau-distance [PDF]

In this paper we first recall the concept of tau-distance on a metric space. Then, we prove a fixed point theorem for singlevalued operators in terms of a tau-distance.fixed point, tau-distance, singlevalued ...
