On the -contractive multi-valued operator and affirmative answer to an open question
Farshid Khojasteh
The current research is devoted to find an affirmative answer to an open question related to contractive operators which have been introduced by Ovidiu Popescu.
A new method for estimating the real roots of real differentiable functions
Hassan Khandani, Farshid Khojasteh
We introduce a new type of Krasnoselskii's result. Using a simple differentiability condition, we relax the nonexpansive condition in Krasnoselskii's theorem. More clearly, we anal…
Some consequences of Caristi's fixed point theorem, partial answers to some known open problems and its applications
Farshid Khojasteh, Erdal Karapinar, Hassan Khandani
In this paper, we show that several extension of Banach contraction principle, can be easily derived from the Caristi's theorem is one of the useful generalization of Banach contra…
Some applications of Caristi's fixed point theorem in metric space
Farshid Khojasteh, Erdal Karapinar, Hasan Khandani
In this work, partial answers to Reich, Mizoguchi and Takahashi, and Amini-Harandi's conjectures are presented via a light version of Caristi's fixed point theorem. Moreover, we in…
Two classes of Meir-Keeler contractions
L. Gavruta, P. Gavruta, F. Khojasteh
In the present paper, we prove that Z-contractions and weakly type contractions are actually Meir-Keeler contractions.
θ-metric spaces: A generalization
Farshid Khojasteh, Erdal Karapinar, Stojan Randenovic
In this paper, using a more generalized inequality instead of triangle inequality, the notion of θ-metric space is introduced. Some important properties of induced topology by such…
Some new common fixed point results of generalized contractive non-self multi-valued mappings
Farshid Khojasteh, Vladimir Rakočević
In this paper, we study some new common fixed point results of generalized contractive non-self multi-valued mappings on complete metric space.
