Abstract |
|
|
| In this paper it is studied a fractional order model for the three stages of HIV epidemics with drug-resistance. The model
includes CD4+ T cells, CTLs, macrophages, and the virus populations. We simulate the model for different values of the fractional
derivative a 2 [0.5,1.0]. The fractional order system untangles generous dynamical characteristics, such as faster transients and slower
evolutions as time increases. These traits are not seen in integer-order models, since they are customary of memory-preserving systems. |
