In this thesis, we are interested in extreme values of certain spatial branching processes such as the branching random walk and the branching Brownian motion. The branching random walk is a particle system that can be described as follows. It starts

The branching random walk is a particle system on the real line starting at time 0 with an initial particle at position 0, then each particle living at time n proceeds to die at time n+1 and give birth, independently from the other particles of gener

Some aspects of the Fisher-KPP equation and the branching Brownian motion

Autor: Brunet, Éric

The Fisher-Kolmogorov, Petrovski, Piscounov equation (FKPP) is a deterministic partial differential equation.It describes the evolution of an invasion front from a stable phase into an unstable phase. Branching Brownianmotion (BBM) is a stochastic Ma

In this thesis, we take interest in the branching random walk, a particles system, in which particles move and reproduce independently. The aim is to study the rhythm at which these particles invade their environment, a quantity which often reveals i
