Extinction time in growth models subject to geometric catastrophes
Valdivino Vargas Junior, Fábio Prates Machado, Alejandro Roldán-Correa
Recently, different dispersion strategies in population models subject to geometric catastrophes have been considered as strategies to improve the chance of po\-pu\-lation's surviv…
Evaluating dispersion strategies in growth models subject to geometric catastrophes
Valdivino Vargas Junior, Fábio Prates Machado, Alejandro Roldan-Correa
We consider stochastic growth models to represent population dynamics subject to geometric catastrophes. We analyze different dispersion schemes after catastrophes, to study how th…
Dispersion as a survival strategy
Valdivino Vargas Junior, Fábio Prates Machado, Alejandro Roldán-Correa
We consider stochastic growth models to represent population subject to catastrophes. We analyze the subject from different set ups considering or not spatial restrictions, whether…
The cone percolation model on Galton-Watson and on spherically symmetric trees
Valdivino Vargas Junior, Fábio Prates Machado, Krishnamurthi Ravishankar
We study a rumour model from a percolation theory and branching process point of view. The existence of a giant component is related to the event where the rumour, which started fr…
Rumor processes on and discrete renewal processes
Sandro Gallo, Nancy L. Garcia, Valdivino Vargas Junior +1
We study two rumor processes on , the dynamics of which are related to an SI epidemic model with long range transmission. Both models start with one spreader at site and ig…
