A Fractional‐Order Complexity Framework for Misinformation Propagation With Fact‐Checking Saturation and Social Vulnerability Dynamics

Complexity, Volume 2026, Issue 1, 2026.
Misinformation spreads through communities in ways that resemble infectious diseases, but existing mathematical models often miss three real‐world complexities: People remember past information (memory effects), some folks are more easily fooled than others (vulnerability), and fact‐checkers can get overwhelmed during big outbreaks (saturation).

A Dynamical Analysis of Supply Chain Systems Under a Dynamic Game Framework Considering Green Technology Innovation

Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
A dynamic model of a green supply chain, comprising two manufacturers incorporating green technology innovation and one product component supplier, was constructed based on a gradient adjustment mechanism. The dynamic behavior of the system was analyzed through stability analysis of equilibrium points and bifurcation conditions, using parameter ...

Well‐Posedness and Stability of a Variable‐Order Discrete Cancer Model

Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
This paper develops and analyzes a nine‐compartment discrete colorectal cancer model governed by a Caputo variable‐order difference operator. The model describes the interactions among epithelial cells, adenomatous polyps, oncogenes, tumor suppressor genes, APC mutations, KRAS mutations, microsatellite instability, inflammatory cells, and ...

Stability Regions and Bifurcation Analysis of a Delayed Tumor Therapy Model Using Oncolytic Virus

International Journal of Differential Equations, Volume 2026, Issue 1, 2026.
We consider the dynamics of a tumor therapy model using oncolytic viruses with time delay. The model is a two‐dimensional system of ordinary differential equations with a delay term that represents the latent period required for viral replication following the infection of tumor cells.

Deterministic and Fractional‐Order Modeling of Potato Disease Transmission Dynamics

International Journal of Differential Equations, Volume 2026, Issue 1, 2026.
Potato plant diseases are a significant concern because they reduce crop yields and quality, putting the global food supply at risk. Our goal in developing this deterministic, fractional‐order epidemic model is to explain the transmission of these diseases by simulating the interactions between susceptible, exposed, infected, treated, and recovered ...

Lyapunov Stability and Optimization of a Fractional‐Order HIV/AIDS Model Coupling Vertical Transmission With Saturated Treatment

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
This research introduces a fractional‐order nonlinear model for the dynamics of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) using Caputo‐type derivatives of noninteger order. Solution properties of the model are investigated by analyzing positivity and boundedness characteristics via the generalized mean value ...

Rich Dynamics of a Predator-Prey System with Different Kinds of Functional Responses

Complexity, 2020
In this study, we investigate a mathematical model that describes the interactive dynamics of a predator-prey system with different kinds of response function. The positivity, boundedness, and uniform persistence of the system are established.

Mathematical Analysis of a Thermo–Mechanical System With Phase Change and Melt–Layer Dynamics: Stability, Regime Transition, and Bifurcation Perspective

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
This study develops a nonlinear thermo–mechanical dynamical model describing the coupled interaction among mechanical motion, heat transfer, viscous dissipation, and melt‐layer evolution during thermally induced phase change. The formulation addresses the limited availability of unified mathematical frameworks capable of simultaneously capturing ...
