[Todos] Seminario de Probabilidad y Estadística Matemática

[Pablo Groisman]

Seminario de Probabilidad y Estadística Matemática.

PROXIMO ENCUENTRO: Miércoles 26 de Septiembre, 12hs
EXPOSITOR: Leonardo Rolla.
TITULO: Two-type particle systems with annihilation
LUGAR: Aula de Seminarios, Dpto de Matemática, 2do piso Pab 1.

RESUMEN:Consider the following interacting particle system with two
types of particles, A and B. Particles perform independent random
walks at rates D_A and D_B, and the interaction is given by mutual
annihilation, i.e., A+B->0. We show that this system is
site-recurrent. We also extend existing results on the lower bound for
the asymtotic density of particles at large times to general i.i.d.
initial states. Most notably we drop the condition that D_A=D_B, which
is a crucial assumption in previously known approaches for two-type
particle systems. Joint work with M. Cabezas and V. Sidoravicius.
