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…
Colonization and Collapse
Fábio Prates Machado, Alejandro Roldán-Correa, Rinaldo B. Schinazi
Many species live in colonies that thrive for a while and then collapse. Upon collapse very few individuals survive. The survivors start new colonies at other sites that thrive unt…
Random walks systems with finite lifetime on
Elcio Lebensztayn, Fabio Machado, Mauricio Zuluaga
We consider a non-homogeneous random walks system on in which each active particle performs a nearest neighbor random walk and activates all inactive particles it encounters…
The fitness of the strongest individual in the subcritical GMS model
Carolina Grejo, Fábio P. Machado, Alejandro Roldán-Correa
We derive the strongest individual fitness distribution on a variation for a species survival model proposed by Guiol, Machado and Schinazi \cite{GMS11}. We point out to the fact t…
