报告摘要：In contrastto a large literature on boundedness results in varioustypes of chemotaxis systems, only fewfindings rigorously detect phenomena related to thespontaneous emergence of large densities,although the latter are among the probably most characteristic features ofevolution driven by chemotactic cross-diffusion. The presentation aims atdiscussing some recent developments in this field, with a focus on methodologicalaspects and, in particular, on analytical challenges inherent to the specialstructure of taxis-type cross-diffusion, which in most cases acts as asuperlinear nonlinearity apparently lacking, however, clear directionalproperties.
