Phase transition for the frog model

O Alves, F Machado, S Popov - 2002‏ - projecteuclid.org
We study a system of simple random walks on graphs, known as frog model. This model can
be described as follows: There are active and slee** particles living on some graph. Each …

From transience to recurrence with Poisson tree frogs

C Hoffman, T Johnson, M Junge - 2016‏ - projecteuclid.org
Consider the following interacting particle system on the d-ary tree, known as the frog model:
Initially, one particle is awake at the root and iid Poisson many particles are slee** at …

Frogs on trees?

J Hermon - 2018‏ - projecteuclid.org
We study a system of simple random walks on T_d,n=(\calV_d,n,\calE_d,n), the d-ary tree of
depth n, known as the frog model. Initially there are Pois (λ) particles at each site …

Frogs and some other interacting random walks models

SY Popov - Discrete Mathematics & Theoretical Computer …, 2003‏ - dmtcs.episciences.org
We review some recent results for a system of simple random walks on graphs, known
as\emphfrog model. Also, we discuss several modifications of this model, and present a few …

Asymptotic shape for the contact process in random environment

O Garet, R Marchand - 2012‏ - projecteuclid.org
The aim of this article is to prove asymptotic shape theorems for the contact process in
stationary random environment. These theorems generalize known results for the classical …

Information Dissemination via Random Walks in d-Dimensional Space

H Lam, Z Liu, M Mitzenmacher, X Sun, Y Wang - Proceedings of the Twenty …, 2012‏ - SIAM
We study a natural information dissemination problem for multiple mobile agents in a
bounded Euclidean space. Agents are placed uniformly at random in the d-dimensional …

Fluctuations of the front in a one dimensional model of 𝑋+ 𝑌→ 2𝑋

F Comets, J Quastel, A Ramírez - Transactions of the American …, 2009‏ - ams.org
We consider a model of the reaction $ X+ Y\to 2X $ on the integer lattice in which $ Y $
particles do not move while $ X $ particles move as independent continuous time, simple …

On an epidemic model on finite graphs

I Benjamini, LR Fontes, J Hermon, FP Machado - 2020‏ - projecteuclid.org
We study a system of random walks, known as the frog model, starting from a profile of
independent Poisson (λ) particles per site, with one additional active particle planted at …

Stochastic orders and the frog model

T Johnson, M Junge - 2018‏ - projecteuclid.org
The frog model starts with one active particle at the root of a graph and some number of
dormant particles at all nonroot vertices. Active particles follow independent random paths …

An improved upper bound for the critical probability of the frog model on homogeneous trees

É Lebensztayn, FP Machado, S Popov - Journal of statistical physics, 2005‏ - Springer
We study the frog model on homogeneous trees, a discrete time system of simple symmetric
random walks whose description is as follows. There are active and inactive particles living …
