A finite-difference discretization preserving the structure of solutions of a diffusive model of type-1 human immunodeficiency virus
Autor: Joel Alba-Pérez, Jorge E. Macías-Díaz
Publikováno v: Advances in Difference Equations, Vol 2021, Iss 1, Pp 1-19 (2021)
Abstract We investigate a model of spatio-temporal spreading of human immunodeficiency virus HIV-1. The mathematical model considers the presence of various components in a human tissue, including the uninfected CD4+T cells density, the density of in

A positive and bounded convergent scheme for general space-fractional diffusion-reaction systems with inertial times
Autor: Joel Alba-Pérez, Jorge Eduardo Macías-Díaz
Publikováno v: International Journal of Computer Mathematics. 98:1071-1097
We consider a multidimensional system of hyperbolic equations with fractional diffusion, constant damping and nonlinear reactions. The system considers fractional Riesz derivatives, and generalizes...

A structure-preserving Bhattacharya method for nonlinear parabolic equations with fractional diffusion and advection
Autor: Jorge Eduardo Macías-Díaz, Joel Alba-Pérez
Publikováno v: Journal of Computational and Applied Mathematics. 354:623-640
In this work, we investigate a parabolic equation with nonlinear reaction, and fractional diffusion and advection terms of the Riesz type. The model under investigation is a fractional generalization of the well-known Burgers–Fisher and Burgers–H

Analysis of Structure-Preserving Discrete Models for Predator-Prey Systems with Anomalous Diffusion
Autor: Joel Alba-Pérez, Jorge Eduardo Macías-Díaz
Publikováno v: Mathematics
Volume 7
Issue 12
In this work, we investigate numerically a system of partial differential equations that describes the interactions between populations of predators and preys. The system considers the effects of anomalous diffusion and generalized Michaelis&ndash
