"Diffusion coefficient and the Speed of Propagation of traveling front solutions to KPP-type problems"

-Abstract
In this talk, we shall concern ourselves with a general reaction-diffusion equation/system in a periodic setting concentrating on reaction terms of KPP-type. Our interest is focused on special solutions called traveling fronts. In particular, we look at how the minimal speed of propagation of such front solutions can be influenced by the different coefficients of the system. For this, an intensive discussion will be alloted specifically on the influence of the diffusion coefficient.
