Fixed Point Theorems for Hybrid Mappings [PDF]

open access: yesThe Scientific World Journal, 2015
We obtain some fixed point theorems for two pairs of hybrid mappings using hybrid tangential property and quadratic type contractive condition. Our results generalize some results by Babu and Alemayehu and those contained therein.

Generalized Caristi's Fixed Point Theorems

open access: greenFixed Point Theory and Applications, 2009
We present generalized versions of Caristi's fixed point theorem for multivalued maps. Our results either improve or generalize the corresponding generalized Caristi's fixed point theorems due to Bae (2003), Suzuki (2005), Khamsi (2008), and others.

Fixed Point Theorems for Almost

open access: yesMathematics, 2018
In this paper, we investigate the existence and uniqueness of a fixed point of almost contractions via simulation functions in metric spaces. Moreover, some examples and an application to integral equations are given to support availability of the ...

Point-valued mappings of sets

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
Let X be a metric space and let CB(X) denote the closed bounded subsets of X with the Hausdorff metric. Given a complete subspace Y of CB(X), two fixed point theorems, analogues of results in [1], are proved, and examples are given to suggest their ...

New common fixed point theorems for multivalued maps

open access: yesApplied General Topology, 2014
Common fixed point theorems for a new class of multivalued maps are obtained, which generalize and extend classical fixed point theorems of Nadler and Reich and some recent Suzuki type fixed point theorems.

On some fixed point theorems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
In this paper we prove a fixed point theorem for inward mappings uing a well-known result of Ky Fan type in Hilbert space setting.

Remarks on Recent Fixed Point Theorems

open access: yesFixed Point Theory and Applications, 2010
Coincidence and fixed point theorems for a new class of contractive, nonexpansive and hybrid contractions are proved. Applications regarding the existence of common solutions of certain functional equations are also discussed.

Near Fixed Point Theorems in Hyperspaces

open access: yesMathematics, 2018
The hyperspace consists of all the subsets of a vector space. It is well-known that the hyperspace is not a vector space because it lacks the concept of inverse element. This also says that we cannot consider its normed structure, and some kinds of fixed

Fixed Point Theorems for Multivalued Mappings Involving α-Function

open access: yesAbstract and Applied Analysis, 2014
We obtain some fixed point theorems with error estimates for multivalued mappings satisfying a new α-ψ-contractive type condition. Our theorems generalize many existing fixed point theorems, including some fixed point theorems proved for α-ψ-contractive ...
