Study of Lagrange Points in the Earth–Moon System with Continuation Fractional Potential

open access: yesFractal and Fractional, 2022
In this work, the restricted three-body system is studied in the framework of the continuation fractional potential with its application on the Earth–Moon system.

Artificial three-body equilibria for hybrid low-thrust propulsion [PDF]

open access: yes, 2008
This paper proposes a new concept of creating artificial equilibrium points in the circular restricted three body problem, where the third body uses a hybrid of solar sail and solar electric propulsion.

Some Dynamic Aspects of a Sextic Galactic Potential in a Rotating Reference Frame

open access: yesApplied Sciences, 2023
This work aims to explore some dynamic aspects of the problem of star motion that is impacted by the rotation of the galaxy, which we model as a bisymmetric potential based on a two-dimensional harmonic oscillator with sextic perturbations.

On the Relationship between Equilibrium Bifurcations and Ideal MHD Instabilities for Line-Tied Coronal Loops [PDF]

open access: yes, 2009
For axisymmetric models for coronal loops the relationship between the bifurcation points of magnetohydrodynamic (MHD) equilibrium sequences and the points of linear ideal MHD instability is investigated imposing line-tied boundary conditions.

Homotopy Perturbation Method for Pneumonia–HIV Co-Infection

open access: yesFoundations, 2022
It is well known that HIV (human immunodeficiency virus) weakens the immune system of individuals, resulting in risk of other infections, such as pneumonia. The most frequent viral pneumonia seen in individuals infected with HIV is cytomegalovirus (CMV).

Modeling and Analyzing Homogeneous Tumor Growth under Virotherapy

open access: yesMathematics, 2023
We present a mathematical model based on ordinary differential equations to investigate the spatially homogeneous state of tumor growth under virotherapy.

Approximate Equilibrium Problems and Fixed Points [PDF]

open access: yesInternational Journal of Analysis, 2013
We find a common element of the set of fixed points of a map and the set of solutions of an approximate equilibrium problem in a Hilbert space. Then, we show that one of the sequences weakly converges. Also we obtain some theorems about equilibrium problems and fixed points.

Existence of almost fixed points for random operators with application in game theory

open access: yesResults in Nonlinear Analysis, 2020
We introduce the notion of the random ε-fixed point for random operators. Then we prove some existence theorems in order to apply this results in game theory for example we will prove existence of ε-random Nash equilibrium in some class of random games ...

Effect of variation of charge in the circular restricted three-body problem with variable masses

open access: yesJournal of Taibah University for Science, 2019
In the present paper, we are concerned by some investigation on circular restricted three-body problem (CR3BP), where we assume that the primaries have variable masses and variable charges. Among the principal tools used in the present study, we cite the

Investigating the Effects of a Fractional Operator on the Evolution of the ENSO Model: Bifurcations, Stability and Numerical Analysis

open access: yesFractal and Fractional, 2023
Recent years have seen an increase in scientific interest in the El Nio/La Nia Southern Oscillation (ENSO), a quasiperiodic climate phenomenon that takes place throughout the tropical Pacific Ocean over five years and causes significant harm.
