DESCRIPTION:Speaker: Sarah Penington\nhosted by M. Beiglböck\, N. Berestyc
 ki\, L. Erdös\, J. Maas\, F. Toninelli\, E. Schertzer\nAbstract: We study
  a particle system in which particles reproduce\, move randomly in space\,
  and compete with each other. We prove global survival as well as a shape 
 theorem describing the asymptotic spread of the population\, when the popu
 lation density is sufficiently large. In contrast to most previous work\, 
 we allow the competition kernel to have an arbitrary\, or even infinite ra
 nge\, whence the term 'non-local competition'. This makes the particle sys
 tem non-monotone and of infinite-range dependence\, meaning that the usual
  comparison arguments break down and have to be replaced by a more hands-o
 n approach. Based on joint work with Pascal Maillard.
