摘要:In this presentation I will introduce a novel class of two-time-scale opinion dynamics models, named the concatenated Friedkin-Johnsen (FJ) model, which describes the evolution of the opinions of a group of agents over a sequence of discussion events. The model is open, in the sense that the agents can participate or less to an event, and the agents are stubborn, with stubbornness that can vary from one event to the next. Concatenation refers to the fact that the final opinions of an event become initial conditions of the next event. It is show that a concatenated FJ model can be represented as a time-varying product of stochastic transition matrices having a special form. Conditions are investigated under which a concatenated FJ model can achieve consensus in spite of the stubbornness. The model is used to describe the 10+ years of international negotiations that lead to the 2015 Paris Agreement on climate change. 
个人简介:Claudio Altafini received a Master degree in Electrical Engineering from the University of Padova, Italy, in 1996 and a PhD in Optimization and Systems Theory from the Royal Institute of Technology, Stockholm, Sweden in 2001. From 2001 till 2013 he was with the International School for Advanced Studies (SISSA) in Trieste, Italy. Since 2014 he is a Professor of Automatic Control in the Dept. of Electrical Engineering of Linkoping University, Sweden. His research interests are in the areas of nonlinear systems dynamics and control, with applications to quantum mechanics, systems biology, social networks and complex networks in general.
