On the existence of accessibility in a tree-indexed percolation model
Cristian F. Coletti, R. J. Gava, Pablo M. Rodriguez
We study the accessibility percolation model on infinite trees. The model is defined by associating an absolute continuous random variable to each vertex of the tree. The…
A process of rumor scotching on finite populations
Guilherme Ferraz de Arruda, Elcio Lebensztayn, Francisco A. Rodrigues +1
Rumor spreading is a ubiquitous phenomenon in social and technological networks. Traditional models consider that the rumor is propagated by pairwise interactions between spreaders…
The role of centrality for the identification of influential spreaders in complex networks
Guilherme Ferraz de Arruda, André Luiz Barbieri, Pablo Martín Rodriguez +3
The identification of the most influential spreaders in networks is important to control and understand the spreading capabilities of the system as well as to ensure an efficient i…
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…
