|Title:||The Probability Of Survival For The Biased Voter Model In A Random Environment|
|Abstract:||In this paper we consider a version of the biased voter model in S, the set of all subsets of Z, in which the recovery rates, δx, x∈Z, are i.i.d. random variables and λ>0 is fixed. We prove a result about the convergence of the probability of survival of the process when λ tends to the critical value λc. As a corollary we find that the critical exponent, β, associated with survival probability is ∞ in contrast to the nonrandom case in which β = 1. © 1990.|
