Michael Winkler  (Universität Paderborn):
Emergence of large densities in chemotaxis-growth systems

We consider variants of the Keller-Segel system of chemotaxis which contain logistic-type source terms and thereby account for proliferation and death of cells. The purpose of the presentation is to discuss how far even despite such additional growth-inhibiting mechanisms, the destabilizing action of chemotactic cross-diffusion therein is yet strong enough so as to enforce the spontaneous emergence of large population densities.
