活动内容摘要：

Aggregation dynamics in Keller-Segel type cross-diffusion systems is known for its sensitivity with respect to total mass sizes in various situations. The intention of the presentation is to firstly recall classical results on associated critical mass phenomena, and to secondly focus on some recent developments concerned with influence of prescribed boundary conditions on effects related to mass criticality.
