Modeling the Spread of Multiple Concurrent Contagions on Networks

Figure 5

State diagram for the Maki-Thompson model of rumor spreading.

The diagram shows the dynamics of a single node. An ignorant node can become a spreader by contacting its neighbors that spread the rumor, with rate . On the other hand, spreader nodes become stiflers by contacting other spreaders or stiflers with rate , or by spontaneously transitioning to the stifler state with rate . The contact-induced transition mechanism is represented by a curvy arrow, whereas the spontaneous transition mechanism is represented by a less curvy arrow. The dashed arrow denotes that , i.e. spreader becomes stifler by contacting other spreaders with rate .
