Stationary distribution of a stochastic SEIR model with infectivity in the incubation period and homestead-isolation on the susceptible under regime switching

Journal of Biological Dynamics
This paper is concerned with a stochastic SEIR model with infectivity in the incubation period and homestead-isolation on the susceptible, which is perturbed by white and colour noises.

Mathematical modelling and analysis of stochastic malaria and COVID-19 co-infection model

Applied Mathematics in Science and Engineering
In this article, we construct and analyse a stochastic mathematical model to study the co-infection dynamics of malaria and COVID-19 in a population. We derive the basic reproduction number associated with the disease-free equilibrium of the stochastic ...

Dynamics of a stochastic modified Leslie–Gower predator–prey system with hunting cooperation

Journal of Biological Dynamics
In this paper, we consider a stochastic two-species predator–prey system with modified Leslie–Gower. Meanwhile, we assume that hunting cooperation occurs in the predators.

Mean square exponential and non-exponential asymptotic stability of impulsive stochastic Volterra equations

Journal of Inequalities and Applications, 2011
In this article, some inequalities on convolution equations are presented firstly. The mean square stability of the zero solution of the impulsive stochastic Volterra equation is studied by using obtained inequalities on Liapunov function, including mean

On stochastic solutions of nonlocal random functional integral equations

Arab Journal of Mathematical Sciences, 2019
In this paper, we use Schauder’s fixed point to establish the existence of at least one solution for a functional nonlocal stochastic differential equation under sufficient conditions in the space of all square integrable stochastic processes with a ...

A neutral stochastic differential system analysis for ABC fractional order with a constant of variations

Applied Mathematics in Science and Engineering
In this article, we explore the existence and uniqueness of mild solutions to fractional stochastic differential equations involving the ABC derivative with the Lipschitz coefficients.
