Abstract

Many different types of dynamics have been studied in network science. Among the dynamics that consider social networks, one crucial subject consists of opinion dynamics. Different approaches consider specific characteristics of the interaction between people. For example, there are models devoted to the formation of echo chambers, also known as social bubbles. Interestingly, some of those characteristics can be found in real systems, such as social networks. Here, we propose the study of these dynamics focusing on the alterations of the topology of the network. More specifically, we intend to analyze the changes in the topology that are induced by a given dynamics that give rise to echo chambers. A particularly important characteristic of the topologies is the presence of communities, which are groups of nodes that are more connected between them, them with the rest of the network. Methodologizelly, in this project, we intend to consider two possibilities of analysis, the temporal evolution and the stationary state of the dynamics.
