Abstract
DIAZ-MARIN, H. G. and OSUNAB, Osvaldo. Periodic solutions for a model of cell population subjected to general periodic radiation. Integración - UIS [online]. 2020, vol.38, n.2, pp.81-91. Epub June 30, 2020. ISSN 0120-419X. https://doi.org/10.18273/revint.v38n2-2020001.
In this work, we considered models with periodic radiation can[1]cer treatment which describe the dynamics of cell populations in a tumor. This may also be used to consider dynamics of healthy tissue under peri[1]odic radiation exposure. We establish the existence of periodic orbits, by using theory of cooperative systems. We give sufficient conditions for the uniqueness of the periodic solution which then becomes a global attractor. Numerical simulations are performed using specific radiation functions to illustrate our analytical findings.
