Analysis of Basins of Attraction in the Pseudo-Newtonian Photogravitational Restricted Four-Body Problem with Asteroid Belt Effects
Vinay Kumar, Rajiv Aggarwal, Nitesh Kumar
Kinematics and Physics of Celestial Bodies, 2026
In this study, we examine the convergence behavior of the Newton–Raphson basins of convergence in relation to the equilibrium points serving as attractors within the framework of the pseudo-Newtonian planar circular restricted four-body problem. This model accounts for the effects of both radiation pressure and the presence of a circular asteroid belt. Our focus lies on determining the positions and assessing the stability of these equilibrium points as the transition parameter, denoted by $$\epsilon $$ , is varied across the range [0, 1]. By employing a multivariate form of the Newton–Raphson iterative algorithm, we draw the basins of convergence across selected two-dimensional planes. A thorough numerical analysis is carried out to illustrate how changes in the transition parameter influence the structure and geometry of these convergence regions. Furthermore, we examine the relationship between the spatial extent of the attraction basins and the number of iterations needed to reach convergence. The results suggest that the behavior of these regions is complex yet deeply engaging, offering rich insights into the dynamics of the system.
Mathematical model for Buruli ulcer and HIV co-infection with optimal control strategy
Ravi Kumar, Rajiv Aggarwal, Tanvi
International Journal of Biomathematics, 2026
In this paper, we investigate the co-infection dynamics of HIV/AIDS and Buruli ulcer, incorporating prevention and treatment strategies for both diseases. The study begins by formulating a co-infection model and separately investigating the HIV and Buruli ulcer sub-models. The basic reproduction numbers for each disease are computed and demonstrate that both sub-models have two equilibrium points, namely, the disease-free equilibrium point and the unique endemic equilibrium point. For both sub-models, the disease-free equilibrium is proven to be both locally as well as globally asymptotically stable when the corresponding reproduction number is less than one, whereas the endemic equilibrium exists when the respective basic reproduction number exceeds one. The full HIV-Buruli ulcer co-infection model is further analyzed, and optimal control analysis is conducted using Pontryagin’s Maximum Principle to minimize the number of infected individuals and the costs associated with prevention and treatment efforts. Numerical simulations are performed with various combinations of control efforts, highlighting the importance of enhanced prevention alongside treatment to reduce the co-infection rates. The results emphasize that both prevention and treatment are critical for effectively controlling the spread of HIV and Buruli ulcer co-infection in the population.

Comparison of Analytical and Numerical Methods to Solve Boundary-Layer Natural Convection Problem for Various Prandtl Number Fluids
Durgesh Kushawaha, Sushil Yadav, Rajiv Aggarwal
Heat Transfer, 2025
Semianalytical approaches such as the Homotopy Perturbation Method (HPM) and Variational Iteration Method (VIM), as well as the Numerical Method, are investigated in this study to solve the boundary‐layer natural convection problem for various Prandlt number fluids on a horizontal flat plate. Nonlinear partial differential expressions can be incorporated into the ordinary differential framework by applying appropriate transformations. The purpose of this study is to show how analytical solutions to heat transfer problems are more versatile and broadly applicable. The results of the analytical solutions are compared with numerical solutions, revealing a high level of approximation accuracy. The numerical findings clearly imply that the analytical techniques can produce accurate numerical solutions for nonlinear differential equations. We analyze the temperature distribution, velocity, and flow field under various conditions. The study found that temperature patterns, velocity distribution, and flow dynamics are all improved by raising the Prandtl numbers. As a result, the thickness of the boundary layer is significantly reduced, leading to an enhanced heat transfer rate at the moving surface. This reduction in boundary‐layer thickness contributes to a more efficient convection process. The study further highlights that the HPM and the VIM both offer highly accurate approximations for solving nonlinear differential equations related to boundary‐layer flow and heat transfer. Among these methods, HPM was found to provide a higher level of precision compared with VIM.

A fractional order age-structured model to study the effect of social awareness on alcohol consumption
Ashutosh Rajput, Rajiv Aggarwal
Physica Scripta, 2025
Alcohol misuse is a widespread societal issue that transcends class boundaries and significantly influencing various facets of life. Accordingly, we have developed a nonlinear mathematical model to explore alcohol consumption, incorporating the novel fractional-order derivative in the Caputo sense to determine the impact of memory effects on drinking behavior. The model examines the influence of adult drinking habits on the youth generation’s drinking habits as well as the role of social and media-driven awareness in shaping this phenomenon. The study has calculated the basic reproduction numbers for both youth and adult populations, which serve as measures of the contagiousness of alcohol consumption. The study has determined an alcohol-free equilibrium point that is locally stable when both reproduction numbers are below one. However, if either reproduction number exceeds one, an additional alcohol-persistence equilibrium point emerges, indicating the potential for a backward bifurcation in the model. Numerical findings suggest that increasing the memory effect by decreasing the value of α can significantly reduce the number of drinkers. Additionally, it is observed that if adult potential drinkers abstain from alcohol and create an alcohol-free environment for the youth, the drinking population can be substantially diminished. Therefore, a combined effort from both the youth and adult populations is essential to prevent binge drinking and reduce the overall drinking population.
Photogravitational Axisymmetric Restricted Five-Body Problem
Prachi Sachan, Rajiv Aggarwal, Amit Mittal
Astronomy Reports, 2025
Abstract In the framework of photogravitational axisymmetric restricted five-body problem (PAR5BP), the existence and stability of the in-plane equilibrium points, the possible regions for motion are explored and analyzed numerically along with good agreement of the graphical results. We have determined the dynamics of the infinitesimal mass in the PAR5BP. We have determined the locations of the libration points (LPs) in the convex configuration. Further, the parametric evolution of the equilibrium points as the function of radiation parameter has been shown. The stability along with the zero velocity surface associated with the libration points are also investigated. It has been observed that none of the libration point is stable for any value of considered parameters.
A novel nonlinear SAZIQHR epidemic transmission model: mathematical modeling, simulation, and optimal control
Abhishek Kumar, Tanvi, Rajiv Aggarwal
Physica Scripta, 2025
This study presents a seven-compartmental nonlinear epidemic model to explore the dynamics and control of the epidemic. The model extends the traditional susceptible-infected-recovered (SIR) framework by including additional compartments for aware, infodemic, hospitalized, and quarantined populations. It also incorporates three Holling type II saturated nonlinear incidence rates to better represent the disease transmission process. The ‘infodemic population’ refers to those spreading misinformation about the disease, its spread, control, and treatment. The study examines disease dynamics in the absence of a vaccine and identifies two key equilibria: the disease-free equilibrium (DFE) and the endemic equilibrium (EE). It is found that the DFE is locally asymptotically stable when the basic reproduction number ( R 0 ) is below one and becomes unstable when R 0 exceeds one. The model’s behavior at R 0 = 1 is analyzed using center manifold theory, revealing a forward bifurcation. Additionally, the existence of a positive endemic equilibrium is confirmed for R 0 > 1 , with no backward bifurcation observed when R 0 ≤ 1 . The EE is also shown to be locally asymptotically stable when R 0 is greater than one. Furthermore, the study formulates and mathematically analyzes an optimal control problem. Finally, numerical simulations are presented to support the analytical results.
