OPTIMAL CONTROL OF A TWO TEAMS PREY-PREDATOR INTERACTION MODEL

, 2015
In this paper, a model of two teams of predators interacting with two teams of preys is proposed. The predator teams help each other and so do the prey teams.

An analysis of hybrid impulsive prey-predator-mutualist system on nonuniform time domains

Computational and Mathematical Biophysics
In this work, we propose a hybrid impulsive prey-predator-mutualist model on nonuniform time domains. We have investigated the permanence/persistence results for the proposed model using the comparison theorems of impulsive differential equations and ...

On the limit configuration of four species strongly competing systems

, 2019
We analysed some qualitative properties of the limit configuration of the solutions of a reaction-diffusion system of four competing species as the competition rate tends to infinity.

Dynamic model of COVID-19 and citizens reaction using fractional derivative

Alexandria Engineering Journal, 2021
This paper presents dynamic model of COVID-19 and citizens reaction from a fraction of the population in Nigeria using fractional derivative. We consider the reported cases from February to June 2020 using fractional derivative. The Stability analysis of

Permanence and global attractivity in a discrete Lotka-Volterra predator-prey model with delays

, 2014
In this paper, we deal with a discrete Lotka-Volterra predator-prey model with time-varying delays. For the general non-autonomous case, sufficient conditions which ensure the permanence and global stability of the system are obtained by using ...

On positive solutions and the Omega limit set for a class of delay differential equations

, 2012
This paper studies the positive solutions of a class of delay differential equations with two delays. These equations originate from the modeling of hematopoietic cell populations. We give a sufficient condition on the initial function for $t\leq 0$ such

Binary trees, exploration processes, and an extented Ray--Knight Theorem

, 2012
We study the bijection between binary Galton--Watson trees in continuous time and their exploration process, both in the sub- and in the supercritical cases.
