Spread of Infection over P.A. random graphs with edge insertion
Caio Alves, Rodrigo Ribeiro
In this work we investigate a bootstrap percolation process on random graphs generated by a random graph model which combines preferential attachment and edge insertion between pre…
Asymptotic Results of a Multiple-entry Reinforcement Process
Caio Alves, Rodrigo Ribeiro, Daniel Valesin
We introduce a class of stochastic processes with reinforcement consisting of a sequence of random partitions , where is a partition of…
Tree Builder Random Walk: recurrence, transience and ballisticity
Giulio Iacobelli, Rodrigo Ribeiro, Glauco Valle +1
The Tree Builder Random Walk is a special random walk that evolves on trees whose size increases with time, randomly and depending upon the walker. After every s steps of the walke…
Agglomeration in a preferential attachment random graph with edge-steps
Caio Alves, Rodrigo Ribeiro, Remy Sanchis
In this paper we investigate geometric properties of graphs generated by a preferential attachment random graph model with edge-steps. More precisely, at each time …
Concentration in the Generalized Chinese Restaurant Process
Alan Pereira, Roberto I. Oliveira, Rodrigo Ribeiro
The Generalized Chinese Restaurant Process (GCRP) describes a sequence of exchangeable random partitions of the numbers . This process is related to the Ewens sampli…
