Some Random Fixed‐Point Theorems for Weakly Contractive Random Operators in a Separable Banach Space
International Journal of Mathematics and Mathematical Sciences, Volume 2021, Issue 1, 2021., 2021 The aim of this paper is to prove a common random fixed‐point and some random fixed‐point theorems for random weakly contractive operators in separable Banach spaces. A random Mann iterative process is introduced to approximate the fixed point. Finally, the main result is supported by an example and used to prove the existence and the uniqueness of a ...

Fixed Point Theorems for Set-Valued Mappings on TVS-Cone Metric Spaces [PDF]
, 2015 In the context of tvs-cone metric spaces, we prove a Bishop-Phelps and a Caristi's type theorem. These results allow us to prove a fixed point theorem for $(\delta, L)$-weak contraction according to a pseudo Hausdorff metric defined by means of a cone ...

AIMS Mathematics, 2020 <abstract> <p>The aim of this paper is to introduce the notion of Suzuki type multivalued contraction with simulation functions and then to set up some new fixed point and data dependence results for these type of contraction mappings. We produce an example to support our results.

A general class of noninstantaneous impulsive fractional differential inclusions in Banach spaces
Advances in Difference Equations, 2017 In this paper we introduce the concept of a PC-mild solution to a general new class of noninstantaneous impulsive fractional differential inclusions involving the generalized Caputo derivative with the lower bound at zero in infinite dimensional Banach ...

Multivalued Problems, Orthogonal Mappings, and Fractional Integro‐Differential Equation
Journal of Mathematics, Volume 2020, Issue 1, 2020., 2020 In this manuscript, we propose some sufficient conditions for the existence of solution for the multivalued orthogonal ℱ‐contraction mappings in the framework of orthogonal metric spaces. As a consequence of results, we obtain some interesting results.

Discrete Dynamics in Nature and Society, Volume 2020, Issue 1, 2020., 2020 In this paper, we approximate the fixed points of multivalued quasi‐nonexpansive mappings via a faster iterative process and propose a faster fixed‐point iterative method for finding the solution of two‐point boundary value problems. We prove analytically and with series of numerical experiments that the Picard–Ishikawa hybrid iterative process has the
