We consider a setting in which two firms compete to spread rumors in a social network. Firms seed their rumors simultaneously and rumors propagate according to the linear threshold model. Using the concept of cascade centrality introduced by [19], we provide a sharp characterization of networks that admit pure-strategy Nash equilibria (PSNE). We provide tight bounds for the efficiency of these ...

Rumor detection has become an emerging and active research field in recent years. At the core is to model rumor characteristics inherent rich information, such as propagation patterns social network semantic post content, differentiate them from truth.
