Opinion Dynamics on Networks
From the spreading of diseases and memes to the development ofopinions and social influence, dynamical processes are influenced heavilyby the networks on which they occur. In this talk, I'll discuss the socialinfluence and opinion models on networks. I'll present a few types ofmodels --- including threshold models of social contagions, voter modelsthat coevolve with network structure, and bounded-confidence models with continuous-valued opinions --- and illustrate how such processes areaffected by the networks on which they occur. I'll also connect thesemodels to opinion polarization and the development of echo chambers inonline social networks.
