We consider a model of an information network where nodes can fail and transmission of information is costly. The formation of paths in such networks is modeled as the Nash equilibrium of an N player routing game. The task of obtaining this equilibrium is shown to be NP-Hard. We derive...

En un sistema formado por una red de nodos emisores y receptores de información, es necesario conocer el estado de señal que tendría cada uno de esos nodos en todo momento con el fin de lograr un flujo de información adecuado. El objetivo de este trabajo es obtener un modelo matemático que...

Longitudinal network data are increasingly available, allowing researchers to model how networks evolve over time and to make inference on their dependence structure. In this paper, a dynamic latent space approach is used to model directed networks of monthly interbank exposures. In this model,...
