On the fixed-circle problem and Khan type contractions
In this paper, we consider the fixed-circle problem on metric spaces and give new results on this problem. To do this, we present three types of F-C-Khan type contractions. Furthermore, we obtain some solutions to an open ...
On the extended hecke groups H¯¯¯¯¯(λq)
Hecke groups H(λq) have been studied extensively for many aspects in the literature, , . The Hecke group H(λ3), the modular group PSL(2,Z ) , has especially been of great interest in many fields of mathematics, for ...
Common fixed points of continuous mappings on s-metric spaces
(Maik Nauka/Interperiodica, 2018)
The aim of this paper is to obtain some common fixed point results on an S-metric space. For this purpose, we prove new generalized common fixed point theorems using the notions of weak commutation, compatibility, and ...
Classification of metallic shaped hypersurfaces in real space forms
We define the notion of a metallic shaped hypersurface and give the full classification of metallic shaped hypersurfaces in real space forms. We deduce that every metallic shaped hypersurface in real space forms is a ...
A new generalization of metric spaces: rectangular M-metric spaces
(Springer Heidelberg, 2018)
In this paper, we introduce the concept of the rectangular M-metric spaces, along with its topology and we prove some fixed-point theorems under different contraction principles with various techniques. The obtained results ...
A new characteristic of Möbius transformations by use of apollonius points of pentagons
In this paper, we give a new characterization of Möbius transformations. To this end, a new concept of ''Apollonius points of pentagons'' is used.

Applications of k-Fibonacci numbers for the starlike analytic functions
The k-Fibonacci numbers Fk,n (k > 0), de #64257;ned recursively by Fk,0 = 0,Fk,1 = 1 and Fk,n = kFk,n + Fk,n #8722;1 for n #8805; 1 are used to de #64257;ne a new class SLk. The purpose of this paper is to apply properties ...
New types of f-c-contractions and the fixed-circle problem
In this paper we investigate some fixed-circle theorems using C ' iric ' ' s technique ( resp. Hardy-Rogers' technique, Reich's technique and Chatterjea's technique) on a metric space. To do this, we define new types of ...
The picard theorem on s-metric spaces
Recently, the notion of an S-metric space is defined and extensively studied as a generalization of a metric space. In this paper, we define the notion of the S-infinity-space and prove its completeness. We obtain a new ...
