内容提要:
Chemotaxis describes the orientated movement of particle toward the chemical concentration gradient. Classical Keller-Segel chemotaxis model exhibits the finite-time blowup behavior which has limited relevance to biology. Hence a large amount of efforts were made in the past few decades to regularize the classical Keller-Segel model so that the regularized models allow the global bounded pattern solutions. Among these models, the volume-filling chemotaxis models, which assumes a priori threshold that cells cannot exceed due to the cell size effect, have been widely used for mathematical studies and biological modelings. In this talk, I will briefly review the ideas of the volume-filling chemotaxis models and show the recent studies on the pattern formation of volume-filling chemotaxis models with numerical simulations. Some open questions will be given.
