Title:A PDE Model for chemotaxis
Seminar:CCMA Luncheon Seminar
Speaker:Yao Yao, Georgia Tech
This talk is an introduction to the afternoon talk. The Keller-Segel equation is a PDE model for chemotaxis (the movement of biological cells or organisms in response to chemical gradients). Mathematically, this equation exhibits an intriguing "critical mass phenomenon", because smooth solutions exist globally in time for all initial data whose mass is below some certain constant, whereas finite-time blow-up always happen if the initial mass is above this constant. In this talk, I will start with a derivation of this equation, and then discuss some useful analysis tools.
