On Stability of Fixed Points for Multi-Valued Mappings with an Application [PDF]

open access: yesAbstract and Applied Analysis, 2014
This paper studies the stability of fixed points for multi-valued mappings in relation to selections. For multi-valued mappings admitting Michael selections, some examples are given to show that the fixed point mapping of these mappings are neither upper

Fixed Point Theorems for Multi-Valued Mappings [PDF]

open access: yesCanadian Mathematical Bulletin, 1980
Two fixed point theorems for multi-valued mappings in a complete, ε-chainable metric space are proved. The theorems, thus established, extend result of M. Edelstein, Peter K. F. Kuhfittig, Hwei-mei Ko and Yueh-hsia Tsai, S. B. Nadler, Jr. and S. Reich.

Fixed point theorems for compatible multi-valued and single-valued mappings [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
The notion of compatibility for point-to-point mappings recently defined by Jungck is generalized to include multi-valued mappings. This idea is used to establish a fixed point theorem for a generalized contractive multi-valued mapping and a single ...

Common Attractive Points of Generalized Hybrid Multi-Valued Mappings and Applications

open access: yesMathematics, 2020
In this paper, we first propose the concepts of (ζ,η,λ,π)-generalized hybrid multi-valued mappings, the set of all the common attractive points (CAf,g) and the set of all the common strongly attractive points (CsAf,g), respectively for the multi-valued ...

Fixed Points of Generalized Contractive Multi-valued Mappings

open access: yesJournal of Mathematical Analysis and Applications, 1995
In a recent paper N. Mizoguchi and W. Takahashi gave a positive answer to the conjecture of S. Reich concerning the existence of fixed points of multi-valued mappings that satisfy a certain contractive condition.

Operator algebras associated with multi-valued mappings [PDF]

open access: yesLobachevskii Journal of Mathematics, 2014
In the paper a new approach is proposed to construction of operator algebras generated by multi-valued mappings on a countable set. We present initial results, discuss the connection with known structures, outline further research directions.

Gregus type fixed points for a tangential multi-valued mappings satisfying contractive conditions of integral type

open access: yesJournal of Inequalities and Applications, 2011
In this article, we define a tangential property which can be used not only for single-valued mappings but also for multi-valued mappings, and used it in the prove for the existence of a common fixed point theorems of Gregus type for four mappings ...

Two Step Modified Ishikawa Iteration Scheme for Multi-Valued Mappings in CAT(0) Space

open access: yesInternational Journal of Analysis and Applications, 2013
The aim of this paper is to prove some strong convergence theorems for the modified Ishikawa iteration scheme involving quasi-nonexpansive multi-valued mappings in the framework of CAT(0) spaces.

New Results on Start-Points for Multi-Valued Maps [PDF]

open access: yesAxioms, 2020
In this manuscript we investigate the existence of start-points for the generalized weakly contractive multi-valued mappings in the setting of left K-complete quasi-pseudo metric space. We provide an example to support the given result.
