报告摘要:

The original Keller-Segel system proposed by Keller and Segel in their seminal papers in 1970-1971 is a system where the diffusion and chemotaxis coefficients are density-dependent and intrinsically correlated.  Most of mathematical studies in the past were focused on its simplified form by assuming that the diffusion coefficient is constant without considering the correlation between the diffusion and chemotaxis. In this series talks, we shall recall the original Keller-Segel system and report some recent progresses made on its global well-posedness and blowup.  Furthermore we shall introduce the density-suppressed motility system which can be regarded a special form of the original Keller-Segel system but has prominent applications in bacterial motion forming the striking strip patterns, and then report some results obtained recently including the global boundedness, pattern formation and traveling waves.
