报告摘要：In this talk, we consider a Keller-Segel-consumption system under homogeneous Neumann boundary conditions in a smooth bounded domain. The main obstacle to analysis results from a possible degeneracy at small signal concentrations. When the motility function possesses sufficiently high regularity, we show that this system has global classical solutions provided that the logistic source fulfills some conditions, while under mild assumptions on the regularity of the motility function, this model admits at least one global weak solution, which becomes smooth after some waiting time.
