Asymptotic behavior of a stochastic combustion growth process

Alejandro RamírezVladas Sidoravicius — 2004

Journal of the European Mathematical Society

We study a continuous time growth process on the d -dimensional hypercubic lattice 𝒵 d , which admits a phenomenological interpretation as the combustion reaction A + B 2 A , where A represents heat particles and B inert particles. This process can be described as an interacting particle system in the following way: at time 0 a simple symmetric continuous time random walk of total jump rate one begins to move from the origin of the hypercubic lattice; then, as soon as any random walk visits a site previously...

Connectivity bounds for the vacant set of random interlacements

Vladas SidoraviciusAlain-Sol Sznitman — 2010

Annales de l'I.H.P. Probabilités et statistiques

The model of random interlacements on ℤ, ≥3, was recently introduced in [Vacant set of random interlacements and percolation. Available at http://www.math.ethz.ch/u/sznitman/preprints]. A non-negative parameter parametrizes the density of random interlacements on ℤ. In the present note we investigate connectivity properties of the vacant set left by random interlacements at level , in the non-percolative regime >∗, with ∗ the non-degenerate critical parameter for the percolation of the vacant...
