Resumo da palestra:

Here cell population dynamics in which each cell can be either in a proliferating or in a quiescent phase is considered. The resulting model is an age-structured reaction-diffusion system. The method of characteristics reduces this model to a coupled reaction-diffusion equation and difference equation. The solution behavior depends on the choice of the non-linearity and the parameters.

We study two important cases:

1) The stability analysis of the unique positive steady state and the existence of a Hopf bifurcation which allow the determination of a stability area, which is related to a delay-dependent characteristic equation.

2) The existence and stability of traveling wave fronts connecting the zero steady state with the unique positive one.
