SUMMARY:Fluid models of swarming behavior - Degond\, P (Paul Sabatier Toul
 ouse III)

CONTACT:Mustapha Amrani
DESCRIPTION:Swarming biological systems (such as fish schools\, insect swa
 rms\, mammalian herds) exhibit large scale spatio-temporal coordinated str
 uctures such as congestions\, waves\, oscillations\, etc. The selforganiza
 tion behavior is not directed encoded in the local interactions between in
 dividuals and emerges when the number of agents is large. In this situatio
 n\, it is legitimate to use fluid models. However\, the relation between t
 he microscopic agent level and the macroscopic fluid level is not as strai
 ghtforward as in the classical gas dynamics case. In this talk\, we will r
 eview a certain number of the mathematical problems posed by these systems
  and some of the answers that can be given.
