RT Journal Article T1 On the mathematical controllability in a simple growth tumors model by the internal localized action of inhibitors A1 Díaz Díaz, Jesús Ildefonso A1 Tello del Castillo, José Ignacio AB We study a model of growth of tumors with a free boundary delaying the tumor region. We take into account the presence of inhibitors and its interaction with the nutrients. We study the approximate controllability of the internal distribution of density of cells, that is proportional to concentration of nutrients, injecting inhibitor in a small inner region.
