Symmetries on Asymmetric Wars: Generalists (HIVs) Versus Specialists (T-cells)

摘要

Antigenic diversity threshold theory by Nowak and May proposes there will be a threshold of diversity for HIV strains in a population dynamics with asymmetric interaction between specialist (T-cells) and generalists (HIVs). This paper revisits the threshold condition from a symmetric point of view. We consider how stability condition for HIVs will be altered when the asymmetry of specialists/generalists is relaxed (made symmetrical). Diversity measure is also considered from a symmetric point of view involving a distance between parameters characterizing strains.
