DESCRIPTION:Branching Brownian motion is a model in which independent part
icles move as Brownian motions and branch at rate 1. Its behavior\, and in
particular the description of what happens near its extremal particles (t
he ones furthest away from the origin) is by now well understood in\ndimen
sion 1. By contrast\, not much is known about the multidimensional case.\n
\nIn this talk I will present the first step towards the goal of obtaining
the limiting extremal point process for the branching Brownian motion in\
nhigher dimensions. This involves in particular finding an analogue of the
so-called derivative martingale\, which plays a crucial role in d=1\,\nan
d studying its convergence.\n \nBased on a joint work with Bastien Mallein
(Université Paris 13).\nSpeakers:\nRoman Stasiński (Department of Stati
stics\, University of Oxford)
