A generalization for the best proximity point of Geraghty-contractions
Bilgili, Nurcan; Karapinar, Erdal; Sadarangani, Kishin (SPRINGEROPEN, 2013)In this paper, we introduce the notion of Geraghty-contractions and consider the related best proximity point in the context of a metric space. We state an example to illustrate our result. -
Generalized alpha-psi contractive mappings in quasi-metric spaces and related fixed-point theorems
Bilgili, Nurcan; Karapinar, Erdal; Samet, Bessem (SPRINGEROPEN, 2014)In this paper, we characterize alpha-psi contractive mappings in the setting of quasi-metric spaces and investigate the existence and uniqueness of a fixed point of such mappings. We notice that by using our result some ... -
A note on common fixed points for (psi, alpha, beta)-weakly contractive mappings in generalized metric spaces
Bilgili, Nurcan; Karapinar, Erdal; Turkoglu, Duran (SPRINGER INTERNATIONAL PUBLISHING AG, 2013)Very recently, Isik and Turkoglu (Fixed Point Theory Appl. 2013:131, 2013) proved a common fixed point theorem in a rectangular metric space by using three auxiliary distance functions. In this paper, we note that this ...
