متن کاملThe Longtime Behavior of Branching Random Walk in a Catalytic Medium
We consider catalytic branching random walk (the reactant) where the state space is a countable Abelean group. The branching is critical binary and the local branching rate is given by a catalytic medium. Here the medium is itself an autonomous (ordinary) branching random walk (the catalyst) – maybe with a different motion law. For persistent catalyst (transient motion) the reactant shows the u...
متن کاملThe longtime behavior of branching random walkin a catalytic
Consider a countable collection (t) of particles located on a countable group, performing a critical branching random walk where the branching rate of a particle is given by a random medium uctuating both in space and time. Here we study the case where the time{space random medium (t) (called catalyst) is also a critical branching random walk evolving autonomously while the local branching rate...
متن کاملLarge Scale Behavior of a System of Interacting Diffusions
We present the explicit derivation of the asymptotic law of the tagged particle process for a system of interacting Brownian motions in the presence of a diffusive scaling in non-equilibrium. The interaction is local and interpolates between the totally independent case (non-interacting) and the totally reflecting case. It can be viewed as the limiting local version of an interaction through a ...
متن کاملInteracting diffusions and trees of excursions: convergence and comparison
We consider systems of interacting diffusions with local population regulation representing populations on countably many islands. Our main result shows that the total mass process of such a system is bounded above by the total mass process of a tree of excursions with appropriate drift and diffusion coefficients. As a corollary, this entails a sufficient, explicit condition for extinction of t...
