Contagion Processes on Time-Varying Networks with Homophily-Driven Group Interactions

Figure 1

The CAD model. In the network, there are two types of nodes, with the blue (green) circles representing type A (B). At each time step, a type A node i becomes active (labeled with solid circle) with the probability . Once the node i is active, it interacts with m nodes randomly chosen from all the other nodes in the network. The purple (orange) dotted line denotes the possible interaction between two nodes with the same type (different types). With the given group interaction probabilities, a simplicial complex with one link and two triangles is generated at this step.
