Empirical assessment of bifurcation regions within new Keynesian models [PDF]
As is well known in systems theory, the parameter space of most dynamic models is stratified into subsets, each of which supports a different kind of dynamic solution.

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 ...

Bifurcation analysis of a multi-transverse-mode VCSEL [PDF]
, 2008 We study the behaviour of a multi-transverse-mode vertical-cavity surface-emitting laser subject to optical feedback in which the optical modes are coupled through the external round-trip. Starting from a delayed partial differential equation description

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.

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 ...

Phenomenological Study of Backward Bifurcation in Epidemiological Models.
, 2005 This thesis is about the phenomenological study of bifurcations in epidemiologicalmodels, in particular, in backward bifurcation. We consider models that exhibit such bifurcation and also consider the factors that cause them.

Journal of Biological DynamicsThe fear preoften leads to changes in the physiological characteristics of the prey. Different stages of prey exhibit different physiological behaviours, such as susceptibility to predator risk, which often leads to Allee effect.
