SUMMARY:Super-Brownian motion among Poissonian obstacles - Amandine Veber 
 (Ecole Normale)

DESCRIPTION:To each positive a\, we associate a random collection of obsta
 cles G_a and a super-Brownian motion in R^d\, with underlying spatial moti
 on given by the law of Brownian motion killed within G_a. The obstacles ar
 e such that\, when a tends to 0\, their intensity grows to infinity but th
 eir radii tend to 0 in an appropriate manner. The result I will present is
  the behaviour of this sequence of super-Brownian motions as a tends to 0\
 , and in particular its (quenched) convergence to a limiting superprocess.
