Clustering in a preferential attachment network with triangles
Angelica Pachon, Robin Stephenson
We study a generalization of the affine preferential attachment model where triangles are randomly added to the graph. We show that the model exhibits an asymptotically power-law d…

Phase transition in preferential attachment-detachment through embedding
Michael Hinz, Angelica Pachon
We study a random graph model with preferential edge attachment and detachment through the embedding into a generalized Yule model. We show that the in-degree distribution of a ver…

On discrete-time semi-Markov processes
Angelica Pachon, Federico Polito, Costantino Ricciuti
In the last years, many authors studied a class of continuous time semi-Markov processes obtained by time-changing Markov processes by hitting times of independent subordinators. S…
