The aim of this work is to study qualitative dynamical properties of a generalized hepatitis B
epidemic model and its dynamically consistent discrete model. Positivity, boundedness, the …

Recently, Hoang and Egbelowo (Boletin de la Sociedad Matematica Mexicana, 2020)
proposed a nonstandard finite difference scheme (NSFD) to get a discrete SIR epidemic …

In this chapter, we propose and analyze a fractional-order hepatitis B epidemic model, which
is an extension of a recognized ordinary differential model. Our main objective is to study …

The co-infection of visceral leishmaniasis (VL) and tuberculosis (TB) patients pose a major
public health challenge. In this study, we develop a mathematical model to study the …

In this work, we study stability properties of a well-known integer-order SEIRS model with
nonlinear incidence and vertical transmission. Firstly, we introduce a simple approach to the …

In this paper, we formulate and analyze a new fractional-order Logistic model with feedback
control, which is different from a recognized mathematical model proposed in our very recent …

The aim of this work is to study global dynamics of target-mediated drug disposition (TMDD)
models and their solutions by nonstandard finite difference (NSFD) schemes. Firstly, we use …

Hepatitis is inflammation of the liver, and one of its types, hepatitis B, is a contagious
infection. Using mathematical models, the nature of the spread of the Hepatitis B virus can …

In this work, we present a mathematically rigorous analysis for the local and global
asymptotic stability of a predator–prey model with Crowley–Martin function and stage …

In a density-dependent single-species population growth model, a simple method is
proposed to explicitly and directly derive the analytic expressions of reliable regions for local …
