Exponential Convergence of the Discrete-Time Altafini Model
Ji Liu, Xudong Chen, Tamer Basar +1
This paper considers the discrete-time version of Altafini's model for opinion dynamics in which the interaction among a group of agents is described by a time-varying signed digra…
Products of Generalized Stochastic Sarymsakov Matrices
Weiguo Xia, Ji Liu, Ming Cao +2
In the set of stochastic, indecomposable, aperiodic (SIA) matrices, the class of stochastic Sarymsakov matrices is the largest known subset (i) that is closed under matrix multipli…
A Stackelberg Game for Multi-Period Demand Response Management in the Smart Grid
Khaled Alshehri, Ji Liu, Xudong Chen +1
This paper studies a multi-period demand response management problem in the smart grid where multiple utility companies compete among themselves. The user-utility interactions are…
A Distributed Algorithm for Solving a Linear Algebraic Equation
Shaoshuai Mou, Ji Liu, A. Stephen Morse
A distributed algorithm is described for solving a linear algebraic equation of the form assuming the equation has at least one solution. The equation is simultaneously solv…
Distributed Evaluation and Convergence of Self-Appraisals in Social Networks
Xudong Chen, Ji Liu, M. -A. Belabbas +2
We consider in this paper a networked system of opinion dynamics in continuous time, where the agents are able to evaluate their self-appraisals in a distributed way. In the model…
On a Modified DeGroot-Friedkin Model of Opinion Dynamics
Zhi Xu, Ji Liu, Tamer Basar
This paper studies the opinion dynamics that result when individuals consecutively discuss a sequence of issues. Specifically, we study how individuals' self-confidence levels evol…
