New Fixed Point Results Inf-Quasi Spaces and an Application
(Hindawi Ltd, 2020) Majani, Hamid; Karapinar, Erdal; Rad, Ghasem Soleimani; Ghasab, Ehsan Lotfali
The main goal of the present paper is to obtain several fixed point theorems in the framework ofF-quasi-metric spaces, which is an extension ofF-metric spaces. Also, a Hausdorff delta-distance in these spaces is introduced, and a coincidence point theorem regarding this distance is proved. We also present some examples for the validity of the given results and consider an application to the Volterra-type integral equation.

Set-Valued Nonlinear Contractive Operators in Pm-Spaces
(Semnan Univ, 2021) Majani, Hamid; Karapinar, Erdal; Rad, Ghasem Soleimani; Ghasab, Ehsan Lotfali
In this paper, we consider some nonlinear contraction for set-valued operators and prove some fixed point results in the case of set-valued operators are ordered-close and not ordered-close, and in the case of set-valued operators are UCAV (LCAV) in quasi-ordered PM-spaces. Moreover, we present two examples and an application to show the validity of the main theorems.
