Rumor Processes on N

We study four discrete-time stochastic systems on N , modeling processes of rumor spreading. The involved individuals can either have an active or a passive role, speaking up or asking for the rumor.

Description
Summary:We study four discrete-time stochastic systems on N , modeling processes of rumor spreading. The involved individuals can either have an active or a passive role, speaking up or asking for the rumor. The appetite for spreading or hearing the rumor is represented by a set of random variables whose distributions may depend on the individuals. Our goal is to understand - based on the distribution of the random variables - whether the probability of having an infinite set of individuals knowing the rumor is positive or not.
