A two-strain ecoepidemic competition model

open access: yes, 2014
In this paper we consider a competition system in which two diseases spread by contact. We characterize the system behavior, establishing that only some configurations are possible.

On the Inverse Problem for a Size-Structured Population Model [PDF]

open access: yes, 2006
We consider a size-structured model for cell division and address the question of determining the division (birth) rate from the measured stable size distribution of the population.

Existence and global stability of positive periodic solutions of a discrete delay competition system

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 38, Page 2401-2413, 2003., 2003
The existence and the global stability of positive periodic solutions of a discrete competition model is studied. The model incorporates time delays and allows for a fluctuating environment. By means of some standard procedures of the topological degree method and the construction of a suitable Lyapunov function, sufficient conditions are obtained to ...

Periodic solution for a delayed three‐species food‐chain system with Holling type‐II functional response

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 64, Page 4057-4070, 2003., 2003
A delayed three‐species periodic food‐chain system with Holling type‐II functional response is investigated. By using Gaines and Mawhin′s continuation theorem of coincidence degree theory, a set of easily verifiable sufficient conditions is derived for the existence of positive periodic solutions to the system.

Dynamical analysis of a reaction–diffusion mosquito-borne model in a spatially heterogeneous environment

open access: yesAdvances in Nonlinear Analysis, 2023
In this article, we formulate and perform a strict analysis of a reaction–diffusion mosquito-borne disease model with total human populations stabilizing at H(x) in a spatially heterogeneous environment.

Existence of Bistable Waves in a Competitive Recursion System with Ricker Nonlinearity [PDF]

open access: yes, 2013
Using an abstract scheme of monotone semiflows, the existence of bistable traveling wave solutions of a competitive recursion system with Ricker nonlinearity is established. The traveling wave solutions formulate the strong inter-specific actions between

Dynamics of two-species delayed competitive stage-structured model described by differential-difference equations

open access: yesOpen Mathematics, 2019
Overf the last few years, by utilizing Mawhin’s continuation theorem of coincidence degree theory and Lyapunov functional, many scholars have been concerned with the global asymptotical stability of positive periodic solutions for the non-linear ...

Modeling Wolbachia infection frequency in mosquito populations via a continuous periodic switching model

open access: yesAdvances in Nonlinear Analysis, 2023
In this article, we develop a continuous periodic switching model depicting Wolbachia infection frequency dynamics in mosquito populations by releasing Wolbachia-infected mosquitoes, which is different from the discrete modeling efforts in the literature.

A note on the existence of non-monotone non-oscillating wavefronts

open access: yes, 2013
In this note, we present a monostable delayed reaction-diffusion equation with the unimodal birth function which admits only non-monotone wavefronts.

Stochastic Analysis of Pine Wilt Epidemic Model With Dynamically Consistent Approximation

open access: yesComplexity, Volume 2025, Issue 1, 2025.
The present study investigated the dynamics of the nonlinear stochastic pine wilt epidemic model. An extension of the stochastic to deterministic model is presented. Equilibria, positivity, boundedness, extinction, and disease persistence were studied rigorously.
