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. 



Behrouz Touri received his B.S. degree in Electrical Engineering from Isfahan University of Technology, Isfahan, Iran in 2006, his M.S. degree in Communications, Systems & Electronics from Jacobs University, Bremen, Germany in 2008, and his Ph.D. degree from the Department of Industrial and Enterprise Systems Engineering of University of Illinois at Urbana-Champaign (2011). He is currently a postdoctoral researcher with the School of Electrical and Computer Engineering of Georgia Tech University. His research interests include random dynamics, applied probability theory, game theory and learning, and decentralized optimization, control, and estimation.
