On cyclic relatively nonexpansive mappings in generalized semimetric spaces

open access: yesApplied General Topology, 2015
In this article, we prove a fixed point theorem for cyclic relatively nonexpansive mappings in the setting of generalized semimetric spaces by using a geometric notion of seminormal structure and then we conclude some results in uniformly convex Banach spaces. We also discuss on the stability of seminormal structure in generalized semimetric spaces.

Characterization of -Semicompleteness via Caristi’s Fixed Point Theorem in Semimetric Spaces [PDF]

open access: yesJournal of Function Spaces, 2018
Introducing the concept of ∑-semicompleteness in semimetric spaces, we extend Caristi’s fixed point theorem to ∑-semicomplete semimetric spaces. Via this extension, we characterize ∑-semicompleteness. We also give generalizations of the Banach contraction principle.
