Existence results for ABC-fractional BVP via new fixed point results of F-Lipschitzian mappings

open access: yesDemonstratio Mathematica, 2022
In this article, fixed point results for self-mappings in the setting of two metrics satisfying FF-lipschitzian conditions of rational-type are proved, where FF is considered as a semi-Wardowski function with constant τ∈R\tau \in {\mathbb{R}} instead of ...

Some new fixed point theorems for nonexpansive-type mappings in geodesic spaces

open access: yesOpen Mathematics, 2022
In this article, we present some new fixed point existence results for nonexpansive-type mappings in geodesic spaces. We also give a number of illustrative examples to settle our claims.

Edelstein Fixed Point Theorem in Neutrosophic Metric Spaces With an Application to an SIR‐Type Epidemic Model

open access: yesInternational Journal of Differential Equations, Volume 2026, Issue 1, 2026.
In this paper, utilizing the concept of neutrosophic metric spaces proposed by Kirisci and Simsek, we establish a fixed point theorem of Edelstein type within this framework. A numerical example is provided to illustrate the validity of the main result. Furthermore, we present an application to a general SIR‐type epidemic model.

Fixed Points of Suzuki Contractive Mappings in Modular b‐Metric Spaces With an Application

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
We introduce the concept of a generalized ZC‐type Suzuki contraction utilizing the generalized framework of metric spaces known as the partial modular b‐metric space in the light of an amorphous binary relation. This conceptual advancement facilitates the derivation of a series of relation–theoretical common fixed‐point theorems, underscoring the ...

Indices of fixed points not accumulated by periodic points

open access: yes, 2016
We prove that for every integer sequence $I$ satisfying Dold relations there exists a map $f : \mathbb{R}^d \to \mathbb{R}^d$, $d \ge 2$, such that $\mathrm{Per(f)} = \mathrm{Fix(f)} = \{o\}$, where $o$ denotes the origin, and $(i(f^n, o))_n = I$.Comment:

On some fixed point results for (s, p, α)-contractive mappings in b-metric-like spaces and applications to integral equations

open access: yesOpen Mathematics, 2018
In this work, we introduce the notions of (s, p, α)-quasi-contractions and (s, p)-weak contractions and deduce some fixed point results concerning such contractions, in the setting of b-metric-like spaces.

Significance of F‐Contraction After Proinov’s Fixed‐Point Results

open access: yesJournal of Function Spaces, Volume 2026, Issue 1, 2026.
Wardowski laid out his idea of an F‐contraction mapping, which provides an imperative generalization of the Banach contraction principle, back in 2012. Although Wardowski’s work has generated considerable interest in fixed‐point theory, motivating many researchers to extend these results to more general spaces, to investigate broader classes of ...
