ω-Interpolative Ćirić-Reich-Rus-Type Contractions
TL;DR: In this article, the concept of ω -admissibility was used to prove fixed point results for interpolate Ciric-Reich-Rus-type contraction mappings.
Book
Fixed Point Theory in Metric Type Spaces
TL;DR: In this paper, the authors present a survey of fixed point results in G-metric spaces and their application to fixed point theory in the setting of G-Metric Spaces.

Antonio Francisco Roldán López de Hierro,Juan Martínez-Moreno,Concepcion Aguilar-Pena,Concepción Roldán López de Hierro +3 more
TL;DR: This paper develops a methodology to solve the fuzzy regression problem introducing a fuzzy partial order and a family of fuzzy distance measures on the whole set of fuzzy numbers and obtains linear and nonlinear models that reach the lowest fuzzy error.
Journal ArticleDOI
New fixed point theorem under R-contractions
TL;DR: In this paper, the notions of R-function and R-contractions were introduced and an ad hoc fixed point theorem was proved for all Meir-Keeler contractions and other well-known classes of contractions.
Journal ArticleDOI
On a new methodology for ranking fuzzy numbers and its application to real economic data
TL;DR: A new technique for ranking fuzzy numbers which is applicable to the whole set of fuzzy numbers is introduced and it is proved that many desired properties are satisfied and numerical examples show reasonable results.
