Moment bounds for IID sequences under sublinear expectations

, 2011
In this paper, with the notion of independent identically distributed (IID) random variables under sublinear expectations introduced by Peng [7-9], we investigate moment bounds for IID sequences under sublinear expectations.

Existence and uniqueness of solution for a fractional hepatitis B model

Computational and Mathematical Biophysics
Understanding the dynamics of infectious diseases using mathematical modeling is essential for developing prevention and control measures. Hepatitis B is still a major public health issue in many places, including Kenya, where the high incidence of ...

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 ...

Analytic solution of a fractional-order hepatitis model using Laplace Adomian decomposition method and optimal control analysis

Computational and Mathematical Biophysics
Infectious illnesses like hepatitis place a heavy cost on global health, and precise mathematical models must be created in order to understand and manage them.

Coexistence for a kind of stochastic three-species competitive models

Open Mathematics, 2019
The coexistence of species sustains the ecological balance in nature. This paper focuses on sufficient conditions for the coexistence of a three-species stochastic competitive model, where the model has non-linear diffusion parts.

A stochastic SICA epidemic model for HIV transmission

, 2018
We propose a stochastic SICA epidemic model for HIV transmission, described by stochastic ordinary differential equations, and discuss its perturbation by environmental white noise.

On the excursions of drifted Brownian motion and the successive passage times of Brownian motion

, 2016
By using the law of the excursions of Brownian motion with drift, we find the distribution of the $n-$th passage time of Brownian motion through a straight line $S(t)= a + bt.$ In the special case when $b = 0,$ we extend the result to a space-time ...
