Fixed Points of Some Asymptotically Regular Multivalued Mappings Satisfying a Kannan-Type Condition

Axioms, 2021
In this paper, we establish some existence of fixed-point results for some asymptotically regular multivalued mappings satisfying Kannan-type contractive condition without assuming compactness of the underlying metric space or continuity of the mapping.

Study of multivalued fixed point problems for generalized contractions in double controlled dislocated quasi metric type spaces

AIMS Mathematics, 2022
The main purpose of this research is to establish a new generalized $ \xi^{\ast } $-Kannan type double controlled contraction on a sequence and obtain fixed point results for a pair of multivalued mappings in left $ K $-sequentially complete double ...

Fixed Point Theorems for Set-Valued Mappings on TVS-Cone Metric Spaces

, 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 ...

Some Combined Relations between Contractive Mappings, Kannan Mappings, Reasonable Expansive Mappings, and T-Stability [PDF]

Fixed Point Theory and Applications, 2009
In recent literature concerning fixed point theory for self-mappings T : X -> X in metric spaces (X,d), there are some new concepts which can be mutually related so that the inherent properties of each one might be combined for such self-mappings.

Solutions of nonlinear difference equations in the domain of ( ζ n ) $(\zeta _{n})$ -Cesàro matrix in ℓ t ( ⋅ ) $\ell _{t(\cdot)}$ of nonabsolute type, and its pre-quasi ideal

Journal of Inequalities and Applications, 2021
We have constructed the sequence space ( Ξ ( ζ , t ) ) υ $(\Xi (\zeta ,t) )_{\upsilon }$ , where ζ = ( ζ l ) $\zeta =(\zeta _{l})$ is a strictly increasing sequence of positive reals tending to infinity and t = ( t l ) $t=(t_{l})$ is a sequence of ...

Fractals of Interpolative Kannan Mappings

Fractal and Fractional
In 2018, Erdal Karapinar introduced the concept of interpolative Kannan operators, a novel adaptation of the Kannan mapping originally defined in 1969 by Kannan. This new mapping condition is more lenient than the basic contraction condition.

Fixed Points for Banach and Kannan Contractions in Modular Spaces with a Graph [PDF]

, 2013
In this paper, we discuss the existence and uniqueness of fixed points for Banach and Kannan $\widetilde G$-$\rho$-contractions defined on modular spaces endowed with a graph without using the $\Delta_2$-condition or the Fatou property.Comment: 12 ...

Toward Scalable Solutions for Silver‐Based Gas Diffusion Electrode Fabrication for the Electrochemical Conversion of CO2 – A Perspective

Advanced Functional Materials, EarlyView.
In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...

Nanoparticle Immunoadjuvant Complexes Augment Germinal Center Responses to Vaccination

Advanced Science, EarlyView.
Scaffolding IL‐21 on the surface of a self‐assembling nanoparticle immunogen drives improved germinal center and humoral immune responses. These nanoparticle immunoadjuvant complexes (NICs) functionally modulate the germinal center driving improved somatic hypermutation and antibody maturation, suggesting this platform has potential utility as a ...
