This talk focuses on the bridge between two research domains: dynamics over networks and networks formation. Due to their close connection to many emerging real-world applications from social networks to biological networks, both of the areas have gained a lot of attention over the past few years. However, less is known when the dynamics over the network affects the network formation which itself affects the dynamics, i.e. there is a feedback loop in such dynamics through changing the network formation. In this talk, we investigate one of these dynamics, i.e. Hegselmann-Krause opinion dynamics, which was motivated by opinion dynamics over social networks but received attentions in other areas such as control theory, robotics, and theory of computer science. We investigate the stability and rate of convergence analysis of this dynamics. We show that in general this dynamics not only converges but also terminates in finite time. We also provide a best know upper bound for the termination time of this dynamics.
