In this article we focused on the mixed convection flow of SWCNT-Water and MWCNT-Water
over a stretchable permeable sheet. The nanofluid occupied porous medium. Darcy's law is …

Terminal value problems of fractional nonlinear systems are studied in this paper. The
existence and uniqueness are given. The regularity of the solution is obtained in the …

In this study, we investigate the impact of memory effects through the application of the
fractal–fractional derivative operator on population dynamics in computer viruses. By …

In this work, we propose and analyze nonstandard finite difference (NSFD) schemes for an
improved hepatitis B virus (HBV) model. Dynamical properties of the constructed NSFD …

The aim of this work is to formulate and analyze nonstandard finite difference (NSFD)
schemes for a recognized virus-patch dynamic model. We introduce a simple and efficient …

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 …

In this paper, we propose a single species logistic model with feedback control and additive
Allee effect in the growth of species. The basic aim of the paper is to discuss how the …

In this paper, we construct and analyze explicit nonstandard Runge-Kutta (ENRK) methods
which have higher accuracy order and preserve two important properties of autonomous …

In this paper, stability analysis which ensures the convergence of a part of the solutions
towards a ball of a class of fractional‐order nonlinear systems is described. Using the …

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 …
