A phase transition in the Susceptible-Infected model on hypernetworks

Gadi Fibich, Guy Rothmann

We derive the master equations for the Susceptible-Infected (SI) model on general hypernetworks with~ $N$ -body interactions. We solve these equations exactly for infinite~ $d$ -regula…

Explicit solutions of the SI and Bass models on sparse ErdÅs-RÃ©nyi and regular networks

Gadi Fibich, Yonatan Warman

We derive explicit expressions for the expected adoption and infection level in the Bass and SI models, respectively, on sparse ErdÅs-RÃ©nyi networks and on $d$ -regular networks.…

Explicit solutions of the Bass and SI models on hypernetworks

Gadi Fibich, Juan G. Restrepo, Guy Rothmann

We analyze the Bass model and the Susceptible-Infected (SI) model on hypergraphs with 3-body interactions. We derive the master equations for general hypernetworks, and use them to…
