Fluctuations of a swarm of Brownian beesn
Original language description
The “Brownian bees” model describes an ensemble of N independent branching Brownian particles. When a particle branches into two particles, the particle farthest from the origin is eliminated so as to keep the number of particles constant. In the limit of N → ∞, the spatial density of the particles is governed by the solution of a free boundary problem for a reaction-diffusion equation. At long times the particle density approaches a spherically symmetric steady-state solution with a compact support. Here, we study fluctuations of the “swarm of bees” due to the random character of the branching Brownian motion in the limit of large but finite N.
