Fixed Point Theorems via α-ϱ-Fuzzy Contraction

open access: yesAxioms, 2019
Some well known results from the existing literature are extended and generalized via new contractive type mappings in fuzzy metric spaces. A non trivial supporting example is also provided to demonstrate the validity of the obtained results.

Some Common Fixed Point Theorems in Generalized Metric Spaces

open access: yesJournal of Mathematics, 2013
First we prove common fixed point theorems for weakly compatible maps which generalize the results of Chen (2012). Secondly, we prove common fixed point theorems using property E.A. along with weakly compatible maps.

Some Common Fixed Point Theorems in Partially Ordered Sets

open access: yesJournal of Applied Mathematics, 2020
The purpose of this paper is to prove some new fixed point theorem and common fixed point theorems of a commuting family of order-preserving mappings defined on an ordered set, which unify and generalize some relevant fixed point theorems.

Common Fixed Point Theorems in Fuzzy Metric Spaces

open access: yes, 2016
In this paper we used the concept of compatible of type (P) in fuzzy metric spaces. Our result generalize earlier results due to Vasuki [18], Chugh and Kumar [3] and others. 2000 Mathematics Subject Classification: 54H25, 47H10.

Fixed point theorems for $alpha$-contractive mappings [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2015
In this paper we prove existence the common fixed point with different conditions for $alpha-psi$-contractive mappings. And generalize weakly Zamfirescu map in to modified weakly Zamfirescu map.

Common fixed point theorems and applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
The purpose of this paper is to discuss the existence of common fixed points for mappings in general quasi-metric spaces. As applications, some common fixed point theorems for mappings in probabilistic quasi-metric spaces are given. The results presented

Wardowski type fixed point theorems in complete metric spaces

open access: yes, 2016
In this paper, we state and prove Wardowski type fixed point theorems in metric space by using a modified generalized F-contraction maps. These theorems extend other well-known fundamental metrical fixed point theorems in the literature (Dung and Hang in

Understanding Fixed Point Theorems [PDF]

open access: yes, 2003
Fixed point theorems are the standard tool used to prove the existence of equilibria in mathematical economics. This paper shows how to prove a slight generalization of Brouwer's and Kakutani's fixed point theorems using the familiar techniques of ...
