Suspended fixed points

open access: yesNuclear Physics B, 2022
We study the orientifold of the ${\mathcal{N}} = 1$ superconformal field theories describing D3-branes probing the Suspended Pinch Point singularity, as well as the orientifolds of non-chiral theories obtained by a specific orbifold $\mathbb{Z}_n$ of SPP.

Inertial Derivative-Free Projection Method for Nonlinear Monotone Operator Equations With Convex Constraints

open access: yesIEEE Access, 2021
In this paper, we propose an inertial derivative-free projection method for solving convex constrained nonlinear monotone operator equations (CNME). The method incorporates the inertial step with an existing method called derivative-free projection (DFPI)

Fixed point theorems for enriched Kannan mappings in CAT(0) spaces

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering, 2023
We present enriched Kannan and enriched Bianchini mappings in the framework of unique geodesic spaces. For such mappings, we establish the existence and uniqueness of a fixed point in the setting of CAT(0) spaces and show that an appropriate ...

On Hilfer generalized proportional fractional derivative

open access: yesAdvances in Difference Equations, 2020
Motivated by the Hilfer and the Hilfer–Katugampola fractional derivative, we introduce in this paper a new Hilfer generalized proportional fractional derivative, which unifies the Riemann–Liouville and Caputo generalized proportional fractional ...

Strong convergence theorems for fixed point of multi-valued mappings in Hadamard spaces

open access: yesJournal of Inequalities and Applications, 2022
With the help of CN-inequality, we study fixed point of multi-valued mappings with closed bounded images and establish some strong convergence theorems involving a countable family of demicontractive mappings in Hadamard spaces.

Fixed point structures [PDF]

open access: yesTransactions of the American Mathematical Society, 1973
A fixed point structure is a triple ( X , P , F ) (X,\mathcal {P},\mathcal {F}) where X is a set, P \mathcal {P} a collection of subsets of X, and F \mathcal {F} a family of multifunctions on X ...

Solutions of fractional order differential equations modeling temperature distribution in convective straight fins design

open access: yesAdvances in Difference Equations, 2021
In this paper, the problem of temperature distribution for convective straight fins with constant and temperature-dependent thermal conductivity is solved by using artificial neural networks trained by the biogeography-based heterogeneous cuckoo search ...

Variational methods to second-order Dirichlet boundary value problems with impulses on the half-line

open access: yesCubo, 2022
In this paper, the existence of solutions for a second-order impulsive differential equation with a parameter on the half-line is investigated. Applying Lax-Milgram Theorem, we deal with a linear Dirichlet impulsive problem, while the nonlinear case is ...
