Abstract:

     In this series of lectures, we shall focus on the  Keller-Segel  bacterior model, which was  first  proposed by Keller and Segel in 1971 to  interpret some wave phenomena of the bacteria pulses  observed in an experiment. I shall introduce some known works on the existence of waves for the system and talk about our recent work on the the local well-posedness of solution for the  Keller-Segel model and the spectral stability of the whole family of explicit traveling waves in some  weighted spaces, by applying some special transformation, detailed spectral analysis and Evan`s function method. It`s a joint work with Yi Li  and Yong Li.
