On a predator-prey system interaction under fluctuating water level with nonselective harvesting
Open Mathematics, 2020 A predator-prey model interaction under fluctuating water level with non-selective harvesting is proposed and studied in this paper. Sufficient conditions for the permanence of two populations and the extinction of predator population are provided.

Lyapunov function for cosmological dynamical system
Demonstratio Mathematica, 2017 We prove the asymptotic global stability of the de Sitter solution in the Friedmann-Robertson-Walker conservative and dissipative cosmology. In the proof we construct a Lyapunov function in an exact form and establish its relationship with the first ...

Multiple time scales method for a two dimensional system with distributed delays
Annals of the West University of Timisoara: Mathematics and Computer ScienceBuilding on the simplified mathematical model derived from the dynamics of the hypothalamic-pituitary-adrenal (HPA) axis, which describes the interactions between ACTH and cortisol through a system of differential equations with distributed delays, this ...

Dynamics of a diffusive HTLV and HIV coinfection model with macrophages, latent cells and two delays
Journal of Biological DynamicsHuman T-lymphotropic virus (HTLV) and human immunodeficiency virus (HIV) are two retroviruses that pose a certain threat to human psychology and physiology. In this paper, we propose a diffusive HTLV and HIV coinfection model with macrophages, two delays,
