The concept of cone b-Banach space and fixed point theorems

open access: yesOpen Mathematics, 2021
In this article, the concepts of cone b-norm and cone b-Banach space are given. Some new fixed point theorems in cone b-Banach spaces are established. The new results improve some fixed point theorems in cone Banach spaces.

Results in Strongly Minihedral Cone and Scalar Weighted Cone Metric Spaces and Applications

open access: yesAnnales Mathematicae Silesianae, 2021
The convergence of sequences and non-unique fixed points are established in ℳ-orbitally complete cone metric spaces over the strongly minihedral cone, and scalar weighted cone assuming the cone to be strongly minihedral.

On θ-generalized demimetric mappings and monotone operators in Hadamard spaces

open access: yesDemonstratio Mathematica, 2020
Our main interest in this article is to introduce and study the class of θ-generalized demimetric mappings in Hadamard spaces. Also, a Halpern-type proximal point algorithm comprising this class of mappings and resolvents of monotone operators is ...

A Note on Brondsted's Fixed Point Theorem [PDF]

open access: yesarXiv, 2023
We show that for the case of uniformly convex Banach spaces the conditions of the Brondsted fixed point theorem can be relaxed.

Hyers-Ulam stability of a nonautonomous semilinear equation with fractional diffusion

open access: yesDemonstratio Mathematica, 2020
In this paper, we study the Hyers-Ulam stability of a nonautonomous semilinear reaction-diffusion equation. More precisely, we consider a nonautonomous parabolic equation with a diffusion given by the fractional Laplacian. We see that such a stability is

Some Fixed Point Theorems Via Combination of Weak Contraction and Caristi Contractive Mapping

open access: yesAnnales Mathematicae Silesianae, 2021
In this paper we introduce some new types of contractive mappings by combining Caristi contraction, Ćirić-quasi contraction and weak contraction in the framework of a metric space.

Existence of zeros for operators taking their values in the dual of a Banach space [PDF]

open access: yesFixed Point Theory Appl. 2004, no. 3, 187--194, 2003
We prove, under certain conditions, the existence of zeros for a weakly continuous operator on a paracompact topological space into the dual of a Banach space.

Asymptotic stability of equilibria for difference equations via fixed points of enriched Prešić operators

open access: yesDemonstratio Mathematica, 2023
We introduced a new general class of Prešić-type operators, by enriching the known class of Prešić contractions. We established conditions under which enriched Prešić operators possess a unique fixed point, proving the convergence of two different ...

The existence and uniqueness of solutions to a functional equation arising in psychological learning theory

open access: yesDemonstratio Mathematica, 2023
The paradigm of choice practice represents the psychological theory of learning in the development of moral judgment. It is concerned with evaluating the implications of several choices and selecting one of them to implement.

On multivalued Suzuki-type θ-contractions and related applications

open access: yesOpen Mathematics, 2020
In this study, we develop the concept of multivalued Suzuki-type θ-contractions via a gauge function and established two new related fixed point theorems on metric spaces. We also discuss an example to validate our results.
