Fisher-type fixed point results in b-metric spaces
(Mdpi, 2019) Alqahtani, Badr; Fulga, Andreea; Karapınar, Erdal; Öztürk, Ali
In this paper, we prove some common fixed-point theorems for two self-mappings in the context of a complete b-metric space by proposing a new contractive type condition. Further, we derive a result for three self-mappings in the same setting. We provide two examples to demonstrate the validity of the obtained results.
On (alpha, psi) -k- contractions in the extended b-metric space
(Univ Nis, Fac Sci Math, 2018) Alqahtani, Badr; Karapınar, Erdal; Öztürk, Ali
In this paper, we introduce a notion of (alpha, psi)-K-contraction in the setting of extended b-metric spaces and investigate the existence of a fixed point. The presented results generalize and unify a number of well-known fixed point theorem mainly in two distinct aspects; in the sense of the contraction conditions and in the frame of abstract spaces.
