DESCRIPTION:Speakers: Dr. EVRIPIDOU\, Charalampos (Special Scientist)\nThe
  Kahan discretization of a Lotka-Volterra system leads to a rational map p
 arametrized by the step size. When this map is Poisson with respect to the
  quadratic Poisson structure of the Lotka-Volterra system we say that this
  system has the Kahan-Poisson property. There is a well known family of Lo
 tka-Volterra systems having the Kahan-Poisson property. Their underlying g
 raph has n vertices 1\, 2\, ...\, n and an arc from i to j precicely when 
 i less than j. We prove that\, modulo permutation of the variables and clo
 nings\, these are the only Lotka-Volterra systems having the Kahan-Poisson
  property.\n\nhttp://indico.fuw.edu.pl/contributionDisplay.py?contribId=52
