On quasi-stationary distributions for stochastic rumor models
Iddo Ben-Ari, Elcio Lebensztayn, Lucas Sousa Santos
This paper examines the quasi-stationary behavior of stochastic rumor processes. Using the results by van Doorn and Pollett (2008), we first prove that the continuous-time Maki--Th…
Representation and Characterization of Quasistationary Distributions for Markov Chains
Iddo Ben-Ari, Ningwei Jiang
This work provides complete description of Quasistationary Distributions (QSDs) for Markov chains with a unique absorbing state and an irreducible set of non-absorbing states. As i…
Can a single migrant per generation rescue a dying population?
Iddo Ben-Ari, Rinaldo B. Schinazi
We introduce a population model to test the hypothesis that even a single migrant per generation may rescue a dying population. Let be a sequence of real numbers in …
Quasistationary Distribution for the Invasion Model on a Complete Bipartite Graph
Iddo Ben-Ari, Clayton Allard, Shrikant Chand +3
The Invasion Model on the complete bibartitle graph was introduced and studied by physicists as a rudimentary model for opinion dynamics on complex networks. We identify the limit…
Self-similarity in an exchangeable site-dynamics model
Iddo Ben-Ari, Rinaldo B. Schinazi
We consider a model for which every site of is assigned a fitness in . At every discrete time all the sites are updated and each site samples a uniform on $[0,1…
Quasi-Stationary Distributions for the Voter Model on Complete Bipartite Graphs
Iddo Ben-Ari, Hugo Panzo, Philip Speegle +1
We consider the discrete-time voter model on complete bipartite graphs and study the quasi-stationary distribution (QSD) for the model as the size of one of the partitions tends to…
