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

Demonstratio 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 ...

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

Open 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.

A numerical schemes and comparisons for fixed point results with applications to the solutions of Volterra integral equations in dislocatedextendedb-metricspace

Alexandria Engineering Journal, 2020
In this article, we propose a generalization of both b-metric and dislocated metric, namely, dislocated extended b-metric space. After getting some fixed point results, we suggest a relatively simple solution for a Volterra integral equation by using the

An Ulam stability result on quasi-b-metric-like spaces

Open Mathematics, 2016
In this paper a class of general type α-admissible contraction mappings on quasi-b-metric-like spaces are defined. Existence and uniqueness of fixed points for this class of mappings is discussed and the results are applied to Ulam stability problems ...

Discussions on the almost 𝒵-contraction

Open Mathematics, 2020
In this paper, we introduce a new contraction, namely, almost Z{\mathcal{Z}} contraction with respect to ζ∈Z\zeta \in {\mathcal{Z}}, in the setting of complete metric spaces.

ANY CYCLIC QUADRILATERAL CAN BE INSCRIBED IN ANY CLOSED CONVEX SMOOTH CURVE

Forum of Mathematics, Sigma, 2018
We prove that any cyclic quadrilateral can be inscribed in any closed convex $C^{1}$ -curve. The smoothness condition is not required if the quadrilateral is a rectangle.

Topological methods in zero-sum Ramsey theory

Forum of Mathematics, Sigma
A landmark result of Erdős, Ginzburg, and Ziv (EGZ) states that any sequence of $2n-1$ elements in ${\mathbb {Z}}/n$ contains a zero-sum subsequence of length n.
